Pioneer Corporation has succeeded in developing a 16-layer read-only optical disc with a capacity of 400 gigabytes for the first time in the world. Its per-layer capacity is 25 gigabytes, which is the same as that of a Blu-ray Disc (BD). This multilayer technology will also be applicable to multilayer recordable discs. This development has bolstered Pioneer's confidence in the feasibility of a large-capacity optical disc, which is expected to become necessary in the near future.

For multilayer optical discs, it has been difficult to obtain clear signals from each recording layer in a stable manner due to crosstalk from adjacent layers and transmission loss. Utilizing the optical disc production technology that it has developed in the DVD field, Pioneer solved these problems by, among other things, using a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback high-quality signals from every layer.

As for the read-out system, Pioneer achieved stability in the playback of recorded signals by employing a wide-range spherical aberration compensator and light-receiving element that can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism. Since the optical specifications of the objective lens, such as NA (Numerical Aperture), are the same as those for the existing BD discs, it is possible to maintain compatibility between the new 16-layer optical disc and the BD discs.

OCZ Technology Group, Inc., a worldwide leader in innovative, ultra-high performance and high reliability memory and computer components, today unveiled the OCZ Core Series SATA II 2.5” Solid State Drives (SSDs). OCZ has gained momentum in this pioneering technology, which uses NAND flash instead of rotating platters as the storage medium, and is a high-performance, highly reliable and energy-efficient alternative to conventional hard disc drives.

The OCZ Core Series delivers the performance and reliability of the latest SSDs at a 50% less price per gigabyte than other high speed offerings currently on the market. For the first time, OCZ is putting SSD technology within reach of the average consumer, and delivering on the promise of SSDs as an alternative to traditional hard drives in consumer targeted mobile applications.

CDRLabs finishes up the week with a review of Lite-On's new EZ-DUB enabled DVD writer, the DX-20A4PU. While affordably priced, this external drive sports some pretty impressive specs including 20x DVD±R, 8x DVD+RW, 6x DVD-RW, 8x DVD±R DL and 12x DVD-RAM writing speeds and a maximum DVD read speed of 16x. The DX-20A4PU  also features many of the technologies we've come to expect from Lite-On including more advanced ones like SmartWrite and OverSpeed. More importantly, its EZ-DUB technology makes copying discs and backing up data a quick and easy process.

ONKYO Corporation has announced that it will release its first Blu-ray Disc Player for the international market in late 2008. This player is designed to partner Onkyo’s high-definition A/V receivers equipped with full HDMI processing of 1080p video and decoding of Dolby® TrueHD and DTS-HD™ Master Audio surround sound formats.

Onkyo was among the first home theater manufacturers to offer full audio and video processing capabilities for HD formats such as Blu-ray Disc. The company’s A/V receivers deliver a complete high-definition experience with onboard decoding of Dolby TrueHD and DTS-HD Master Audio codecs. The release of this Blu-ray Disc player will be timely given that the second-generation of high-definition-capable Onkyo A/V receivers is now available.
