Ricoh unveils recordable CDs supporting all standard writing formats.

Ricoh has introduced a recordable compact disc (CD-R) technology with incremental write capabilities. The company's new product line, which includes CD-R drives, signal processors, discs and related software, signifies Ricoh's full-scale entry into the computer compact disc field.

Unlike conventional CD-ROM (read-only-memory) systems, Ricoh's new CD-R technology allows data of varying length to be recorded by users, similar to magnetic storage media. Taking advantage of the near-line input capability inherent in CD-R, Ricoh has concentrated its development efforts on products for computer industry applications where frequent user updating is required.

Ricoh's new RS-9200C CD-R drive is capable of supporting incremental writing, track writing, and multisession writing formats to discs conforming to ECMA168 standards. The new drive meets all Orange Book Part 2 guidelines and provides a SCSI-II interface. Information that is recorded on the CD-R media by the RS-9200CD drive can be played back with any conventional CD player.

The RS-9200CD drive has a recording and transfer rate of 150 kilobytes per second, with an average access speed of less than 500 milliseconds. Its recording capacity is 650 megabytes. The RS-9200CD is a compact desktop unit, measuring approximately 8 1/4" wide by 12 1/4" deep by 5" high, and weighing about 14.3 pounds.

Ricoh is currently accepting orders for the RS-9200CD drive, and expects to begin OEM shipments to systems manufacturers and other customers in the first quarter of 1993. The new drive has a suggested single unit price of $4,165, and initial production is expected to be approximately 500 drives per month.

In a related development, Ricoh also introduced a new CD-R signal processor, the RF5C119, a single-chip LSI that provides all the core control requirements of a CD drive. This powerful component implements a variety of functions necessary to read and write to discs conforming to standards of CD-DA (digital audio), CD-ROM (read-only-memory) and CD-I (interactive).

Ricoh's RFSC119 signal processor conforms to Orange Book Part 2 standards, supports EFM/CIRC encoding and decoding, and includes an ATIP decoder circuit. It is designed for a 5V CMOS process and is currently available from Ricoh in a 100-pin flat package, at a suggested list price of $100.

Ricoh's recordable CDs conform to the standards of Orange Book Part 2, have a wide jitter margin and will resist high temperature and humidity. For more information, contact Ricoh Corporation, 5 Dedrick Place, West Caldwell, NJ 07006, 201/882-2000.
