Last Updated From the Excite Site, news on "new" phase change material from TDK. Is this really new material or something that is liceensed from ECD? 7:38 PM ET October 14, 1998 TDK Breakthrough Heralds The Age Of Home DVD Video Recording PORT WASHINGTON, N.Y. (BUSINESS WIRE) - The era of home DVD video recording drew nearer last week as TDK announced a major breakthrough in phase-change recording material critical to the development of a rewritable DVD disc capable of playback on DVD-Video players and computer DVD-ROM drives. At technology seminars hosted by the company in New York and San Francisco, TDK demonstrated working prototypes of a 4.7GB DVD-RW disc using the company's new ReCom (Rewritable/Compatible) recording material. The disc, which was recorded in the company's research laboratory, displayed high-quality video programming when played on a variety of consumer DVD-Video decks. According to a TDK research engineer who made the presentation last week, the new ReCom recording material will prove critical in the creation of compatible/rewritable DVD-RW discs, as well as increasing the capacity of today's DVD-RAM discs from 2.6 GB to 4.7 GB (DVD-RAM discs are not playback-compatible with DVD-Video and DVD-ROM). Compounded of silver, antimony, tellurium and indium, ReCom is unique in its ability to form ultra-small, highly precise data marks in response to very rapid laser pulses. In addition, the material is extremely well-suited to multiple rewrite operations, and has been tested in excess of 1,000 record/overwrite cycles. In a related announcement, TDK also disclosed that it has succeeded in creating a write-once DVD-R disc with a full 4.7 GB capacity, up from the 3.95 GB capacity of current DVD-R media. Write-once DVD-R discs are playback compatible with DVD-ROM and DVD-Video drives, and with 4.7 GB capacity - the same as pressed read-only DVD discs - the new TDK DVD-R discs will be a more flexible and convenient medium for multimedia producers and DVD authoring professionals. TDK has achieved 4.7GB capacity in its DVD-R discs by use of its proprietary MSI metal-stabilized cyanine dye technology, which was retuned for the shorter laser wavelength necessary for higher-density optical recording. TDK, which pioneered in the development of cyanine-based recording materials for its line of Certified Plus CD-R discs, noted that other types of organic dyes currently used by some CD-R manufacturers do not have the properties necessary to create 4.7 GB DVD-R discs. According to Mr. Kuni Matsui, president of TDK Electronics Corporation, recordable optical media represents the future for many business and entertainment applications. Said Mr. Matsui, "The success of CD-R has proven beyond a doubt that optical disk-based recording is the way the market will go. This year, industry-wide sales of CD-R discs in the U.S. will total some 150 million pieces, and should double within three years. And as recordable DVD technology begins to reach home and desktop users - especially with media that is playback compatible with DVD-Video and DVD-ROM drives - the market will grow even faster. Though there are many hurdles that must be overcome before the age of home video recording on DVD can be achieved - not least of which are the needs of copyright holders and content creators -- the technologies to create a disk-based optical recording universe are rapidly coming into place. It is in this universe that TDK sees its future." TDK currently offers a broad variety of recordable DVD media, including 3.95 GB DVD-R discs as well as 2.6 GB (single-sided) and 5.2 GB (double-sided) DVD-RAM discs. The company expects to offer 4.7 GB DVD-R and DVD-RAM discs in the 1st and 4th quarters of 1999, respectively. Timing for the introduction of DVD-RW discs must await publication of standards for the format, but market introduction could be as early as the 2nd quarter of 1999.
