Holographic Optical Disc Technology Emerges – InPhase Technologies of Longmont, Colorado has developed a holographic storage technology which raises the capacity of a single optical disc from the 15 GB of HD DVD and 25 or 50 GB of Blu-ray to 300 MB. So far the discs are WORM (Write Once Replay Many), but the company is working on rewritable discs as well as increasing the capacity much further. InPhase is working with Maxell and using their Tapestry disks, which cost $100 to $125 each. The discs have an effectively limitless shelf life and durability and therefore InPhase is targeting the archiving market. The discs spin very slowly, about like the second hand on a watch. The initial target is for telecasters, and the first to make use of the technology will be a pair of Reno stations. If costs could eventually be brought down, Tapestry sounds like a superior hi-def solution to either Blu-ray or HD DVD.

Blu-ray Recorder Released – Sony has launched the first Blu-ray recording device for consumers, the BWU-100A, which is a standard-appearing internal drive for computers. While with only a 25 GB capacity now, 50 BG is expected shortly. The unit is aimed at professional moviemakers but will probably be picked up by computer users for its much higher backup capacity than DVD, as well as for making a do-it-yourself DVR box for storing HDTV programs. There is as yet no recordable HD DVD device.

New Car Sound Options
– Seeing the popularity of aftermarket installations of audio and video systems in vehicles, automakers are beginning to offer extensive auto sound systems in conjunction with electronics companies such as Bose, Pioneer, B & O, Alpine and Eclipse. As a result, aftermarket shipments of CD head units are down this year by 10%.  The work has become more difficult for the car stereo shops.  The dashboard design of most new cars doesn’t support aftermarket replacement of the original audio system without extremely invasive (and expensive) installation procedures. The head units have become increasingly hard to work with. Systems have also gotten much more complex. Popular options today can include remote starting, video and navigation systems, surround sound speakers, satellite radio, MP3 and iPod connections, Bluetooth hands-free cell phone kits, and back-up sensors.

A Kenwood spokesman warned that most of the new car systems aren’t exactly cutting-edge. The actual speakers are cheap, and digital processing is used to compensate for anomalies. The Kenwood exec points to the introduction of the compact disc 25 years ago as the catalyst for all these upgrades. GPS systems are now becoming a must-have for many. Some car makers are seeking to give consumers what they want by building in an interface adapter that allows connecting aftermarket units into the OEM dash system.  The next step is offering the ability to make such connections wirelessly, as from, say, an iPod or portable GPS unit.
