Anticipating what it sees as the forthcoming demand for DVD recording devices, Memorex just announced a bunch of new writeable disks for those who can afford the drives. The company says the media will be compatible in new devices that use either DVD-R or DVD-RAM disks. The DVD-R version of the product will hold 4.7 GB of data packaged in a single configuration and carry a suggested retail price of $19.99. The DVD-R disc is a single-sided, "General Use" type with write-once capability. Of the two types of DVD-R media (General Use or Authoring), General Use will be compatible with most new Video DVD-recorder/players and newer DVD-R computer writers. Authoring type media requires a finer width reading and writing laser and is not compatible with General Use media. Memorex DVD-R 4.7GB packages will be marked "General Use 650 Nanometer" for the laser width and "120 Minute Video" indicating the recording time capacity of standard or NTSC video. The DVD-RAM products will be offered in single-sided 4.7GB and double-sided 9.4GB formats. Both will be packaged in single configurations and carry suggested retail prices of $34.99 and $39.99 respectively. The 4.7GB DVD-RAM media is contained in a Type 2 cartridge, letting you know that it is removable. The 9.4GB DVD-RAM version is contained in a Type 1 cartridge and is designed for drives that will accommodate the enclosure. Memorex says the DVD-RAM discs allow over 1000 rewrites and will be clearly marked for capacity and cartridge type.
