Air Display Enables iPad as External Monitor for Your Mac

Air Display turns iPad into an external displayPR: Ever wish you had an extra display for your computer? There's an app for that. With Air Display, you can use your iPad as a wireless display for your Mac OS X computer. Developed by Avatron Software, home of the popular Air Sharing apps, Air Display lets you position your iPad next to your computer, drag windows onto it, and interact with those windows as you would on any other computer display.

Air Display's performance is extremely responsive, employing a clever dynamic compression algorithm. On a typical Wi-Fi network, mouse cursor refreshes are indistinguishable from a wired mouse.

Air Display works in both landscape and portrait configurations. Just rotate your screen, and it automatically reconfigures.

Air Display makes a laptop much more useful. Adding the iPad's 1024x768 display nearly doubles the screen area of a MacBook Air or 13" MacBook.

Air Display not only gives you a wireless computer screen extender, but also works as a tablet input device. You can use your finger to draw directly on the screen's surface. Try it with a Mac calculator app, painting tool, or music control surface!

Some great uses for Air Display:

  • Fill your iPad screen with your utility apps, like iChat, Mail, iCal, and Calculator.
  • Amaze your friends by playing Flash animations on your iPad!
  • Graphic design: Make Photoshop and Illustrator usable on your laptop by putting your tool palettes on the iPad screen.
  • Music: Use your iPad as the ultimate control surface for Logic or Pro Tools.
  • Programming: Use the extra display area for such auxiliary development tools as Console, Terminal, and the Debugger.
  • Business: Move all of your iWork and Office palettes and inspector windows onto the iPad, and let your document fill the screen.
  • Find your own uses.

On first launch, Air Display presents easy instructions for downloading and installing the companion Mac software.

System Requirements:

  • Compatible with iPad.
  • Requires iPhone OS 3.2 or later.

The Air Display support software is only compatible with Mac OS X. Windows support software will be available soon.

In addition, on Mac OS X, Air Display requires 10.6 (Snow Leopard) or later, on an Intel CPU. Both 32-bit & 64-bit systems are supported.

Avatron will shortly be releasing a Mac OS X software update that supports Leopard (Mac OS X 10.5.8) as well.


Hitachi Travelstar Ultra-Slim 7mm 7200 RPM Laptop Hard Drive

Hitachi Travelstar Z7K320PR: A high-performance, quiet hard disk drive (HDD) solution for mobile applications, Hitachi's new Travelstar Z7K320 2.5" mobile hard drive features low Profile - 7mm thickness for design flexibility, 7200 RPM rotation speed for faster data access, quiet operation for a richer audio-listening experience, and is available in 160GB, 250GB, and 320GB capacities.

Travelstar Z7K320 is the industry's first 7200 RPM, 7mm, 2.5" hard drive with capacities ranging from 160GB to 320GB. Seven millimeters equals about one-quarter inch (specifically 0.27559"), which is also about 25% thinner than the 9.5mm drives used in today's thin notebook computers. The 320GB per platter one-disk models are designed as a direct replacement for standard 9.5mm hdds, for use in notebook PCs, external storage, and compact systems. The Z7K320 offers design flexibility to accommodate new thinner and more robust devices/systems and delivers up to 18% better application performance than 5400 PM models of the same capacity. Along with continued focus on superior shock protection and low-power consumption, Hitachi delivers best-of-breed acoustics. Hitachi offers optional hard-drive-level encryption for increased data security and models with enhanced availability to deliver high-performance storage for non-stop environments. Travelstar Z7K320 provides the right balance of performance and capacity to meet the multi-tasking needs of commercial and consumer users on the go.


  • New 7mm z-height for greater design flexibility
  • 7200 RPM high-performance HDD
  • Up to 320GB of capacity
  • Best-of-breed acoustics
  • Low power consumption
  • Halogen-free for eco-friendly footprint
  • Serial ATA 3Gb/s
  • Encryption options, including Trusted Computing Group (TCG) Opal
  • Enhanced-availability (EA) models for >>applications needing around-the-clock access in lower-transaction environments

Data security option

Travelstar Z7K320 is the fourth generation to feature optional Bulk data encryption (Bde) for hard-drive-level data security. Hitachi has designed these self-encrypting drives to the Trusted Computing Group (TCG) Opal storage security specification, which is expected to become an industry standard. With Bde, the data is scrambled using a key as it is written to the disk, then descrambled with the key as it is retrieved, giving users the highest level of data protection available. It also speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data on the drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.

Enhanced Availability (EA)

For 24x7 access to data, Hitachi provides enhanced-availability models of the Travelstar Z7K320 that deliver 24x7 access to information for data-intensive applications requiring round-the-clock operation. The new, slimmer profile provides for additional cooling, especially important in dense blade server designs. The Z7K320 provides high capacity, performance, and durability on a proven platform for quality and reliability. EA models support the stringent demands of "always-on" applications in lower-transaction environments.

Applications / Environments

  • Notebook and ultra-portable PCs
  • Compact desktop PCs
  • External storage
  • Gaming PCs
  • Compact video devices
  • Blade servers (EA)
  • Network routers (EA)
  • Video surveillance (EA)
  • Compact RAID systems (EA)

The Travelstar Z7K320 series drives are projected ship in volume in July and August.

Hitachi-LG HyDrive: World's First Hybrid Solid State/Optical Drive

PR: Hitachi-LG Data Storage Inc. has announced HyDrive, the world's first solid state drive (SSD) embedded optical disc drive (ODD). HyDrive will be available in the Far East in August 2010, installed on the Family PC MN 102-O from MONEUAL, and is projected to ship worldwide in March 2011.

Hitachi-LG HyDriveThe SSD capacity will be 32 GB and 64 GB for the 1st generation, and up to 256 GB with the 2nd generation, which will be ready for mass production in March 2011 and have even faster SSD performance, moving from SATA 3.0 Gbps to the SATA 6.0 Gbps interface.

HyDrive performance stands to reach its full potential on performance notebooks, delivering data handling capabilities currently unavailable to moblie users.

HyDrive enables a total storage solution on the computer, using the advantages of three storage device types - conventional hard drives, solid state drives, and optical drives - without added space on the motherboard, and modification of system architecture is limited to replacing the existing ODD. Only HyDrive enables this through an identical framework to that used in conventional ODDs.

HyDrive offers hard disk drive (HDD) performance boosting in two ways.

One is through using the entire SSD as a cache by the HLDS filter driver. The other is by having Windows and Microsoft Office applications installed and the remaining capacity serve as a cache.

Having 32GB of SSD suffices in accommodating Windows and Microsoft Office applications, offering consumers the enjoyment and stress-free experience of usage with pure SSD speeds.

HyDrive also enables a smaller hardware footprint (7-9"tablet PCs such as the Ultra Mobile PC, for example) by removing the HDD or SSD from the motherboard and just having HyDrive with its SSD as primary storage.

HyDrive can offer users 30-60% faster booting, shutdown, and application loading on optimized hardware.

Other features have been developed for a combination of ODD and SSD benefits, such as robust media readability which differentiates readability and playability of data, audio, or movie discs from other ODDs in the market, using the dedicated burning feature. It provides smooth and seamless playback even of discs in poor condition due to scratches and fingerprints.

Much more to come with the next generation HyDrive

HLDS have been working with their partners AMD, ASUS and MONEUAL to achieve a successful market launch.

"AMD's latest 8-series chipsets have both the required hardware and driver support for HyDrive, including SATA port multiplier support, which enables combined optical and solid state functionality in the HLDS HyDrive", said AMD's Niles Burbank, Senior Product Manager for AMD's Platform Solutions.

MONEUAL will deliver the very first launch of HyDrive? through their Family PC MN 102-O in August 2010, showcasing home theater quality performance. HyDrive is capable of playing back CD, DVD, and Blu-ray media, and fast booting and application loading with 32 GB SSD.

ASUS plans to launch the 1st generation HyDrive on their Eee Top range, and the 2nd generation HyDrive global debut on the N61DA notebook after testing HLDS samples.

HyDrive is a trademark of Hitachi-LG Data Storage, Inc. Other company and product names may be trademarks of their respective owners.

Editor's note: No official price has been announced yet, but rumor has it that HyDrive could add $200 to the price of a typical notebook. This does not appear to be available in a slot-loading configuration, which means that Apple probably won't consider using them. Besides, Apple doesn't yet support Blu-ray on anything. dk
