Hitachi America ships 24X data rate CD-ROM drive for computer OEM and upgrade markets; 24X maximum data rate and 90ms access times deliver fastest possible CD performance in personal computers.BRISBANE, Calif.--(BUSINESS WIRE)--July 1, 1997--Hitachi America, Ltd. today announced that it is shipping the CDR CDR - Commander CDR - Compact Disc Recordable CDR - CorelDRAW File (file extension) CDR - Call Data Record CDR - Call Detail Recording CDR - Call Detail Reporting CDR - Call Dial Rerouting CDR - Call-Detail Record CDR - Canadian Dachshund Rescue (Canada) CDR - Cancer Detection Rate CDR - Cargo Delivery Receipt CDR - Cargo Drop Reel CDR - Cash Data Retrieval CDR - Center for Dairy Research CDR - Center for Design Research (Stanford)-8330, a 24X maximum data rate CD-ROM drive for personal computers. The new drive utilizes advanced signal processing electronics and Constant Angular Velocity (storage) constant angular velocity - (CAV) A disk driving scheme in which the angular velocity of the disk is kept constant. This means that the linear velocity of the disk be larger when the reading or writing the outer tracks. The disadvantage of this technique is that the read/write speed varies from track to track. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) this allows the full potential of the drive is used. technology to achieve data rates ranging from 1,500 KB/sec. to 3,600 KB/sec., with data access times as low as 90 ms. Hitachi was the first CD-ROM manufacturer to use Constant Angular Velocity (CAV) technology, which eliminates the variable spindle motor speed used in older CD-ROM drives. By spinning the disc at a constant rate, equivalent to a 10X data rate drive in the CDR-8330, the drive is quieter and more reliable than drives spinning at faster speeds. Constant motor speed also eliminates the need for settling of the optical pickup after seeking data, resulting in an improved access rate compared to drives using older CLV (Constant Linear Velocity (storage) constant linear velocity - (CLV) A disk driving scheme in which the linear velocity of the disk is kept constant. This requires that the angular velocity of the disk be larger when the reading or writing tracks closer to the axis. The advantage of this technique is that the read/write speed is constant. However, as mechanical stability puts an upper limit on the angular velocity (and not the linear velocity) using the same linear velocity throughout, i.e.) technology. "Even as the market begins its transition to DVD drives A Lotta X's This is the label from a Memorex combo DVD and CD drive in 2005. Each "X" number means the speed for that format is X times 1.35MB for DVDs and 150KB for CDs., our OEM and distribution channel customers are seeing demand for improved CD-ROM drive performance and reliability," said Werner Glinka, Director of Marketing for the Storage Products Group of Hitachi America, Ltd. "The CDR-8330 meets this demand, providing maximum performance for owners of new, Pentium-class systems using CD-based multimedia applications, including productivity software, reference materials, educational software, and games." The CDR-8330 drive is designed for Windows 3.X and Windows 95 systems. It uses the E-IDE (ATAPI PIO Mode (Programmed Input/Output mode) The data transfer mode used by IDE drives. These modes use the CPU's registers for data transfer in contrast with DMA, which transfers directly between main memory and the peripheral device. For transfer rates, see IDE.  4) bus interface and supports DMA (Direct Memory Access) Mode 2 to minimize the effect of drive operations on CPU performance. Physical dimensions are 146 mm X 41.3 mm X 190 mm, and the drive has a weight of approximately 1 kg. The CDR-8330 drive supports all standard 650 MB capacity CD-ROM formats, including Mode 1 and Mode 2 discs, Photo CD, Audio CD, Data and Audio Mixed Mode, and CD-Extra. CD-Recordable and CD-Rewritable media can also be read in the drive. The CDR-8330 drive is marketed in North America by the Computer Division of Hitachi America, Ltd. While Hitachi's principal customers are personal computer OEMs, the company expects that upgrade kit vendors will package the drive for resale directly to end-users at competitive retail prices. The Computer Division of Hitachi America, Ltd. sells high-capacity, high-performance hard disk drives, CD-ROM, and DVD drives through its Storage Products Group. The Computer Division is part of Hitachi Americas Converging Technologies Group, which markets a broad range of electronic hardware and software products, including semiconductors, storage devices, printers, monitors and flat panel displays. Hitachi America, Ltd., a wholly owned subsidiary of Hitachi, Ltd., Japan, markets and manufactures a broad range of electronics, computer systems and semiconductor products, and provides industrial equipment and services throughout the United States. Hitachi, Ltd., headquartered in Tokyo, Japan, is the world's leading global electronics company, with fiscal 1996 consolidated sales (ending March 31, 1997) of $68.7 billion. The company manufactures and markets a wide range of products, including computers, semiconductors, consumer products and power and industrial equipment. CONTACT: Hitachi America, Ltd.
