New CD-ROM Drive from Toshiba
Toshiba America Information Systems, Inc., Disk Products Division (TAIS, DPD) has introduced a fourth-generation series of CD-ROM drives that set net standards for reliability, performance, and protection from contamination.
The new XM-3300 Series CD-ROM drives feture a 325ms average access time--the fastest in the industry--and a new design that solves the industry-wide problem of drive contamination. Drive contamination is caused by foreign particles (dust, etc.) that enter the drive from the environment. Over time, these particles accumulate on the optics, resulting in increased error-correction code (ECC) activities and a decrease in performance. The accumulation of particles requires more frequent maintenance to clean the optics for continued drive operation.
The new XM-3300 Series CD-ROM drives employ a sealed design combined with automatic lens cleaning capabilities to prevent drive contamination and extend the time required between maintenance for cleaning by as much as a factor of five.
This new contamination-free design, developed by Toshiba, safeguards the drive from contamination in two ways. First, the drive itself is in a fully sealed enclosure which prevents environmental contaminants from entering the drive. Until now, particles have been able to enter the drive through service/connector openings.
Second, contamination is further prevented through a closable front door that completely covers the caddy slot. This new door seals the disc entry to prevent contaminants from entering through the front opening.
"We have developed a drive that not only meets user performance requirements, but further addresses the industry-wide issue of drive contamination," said Jerald Higgins, vice president marketing, optical disc drives, TAIS, DPD. "Environmental particles have been able to enter a CD-ROM drive and interfere with operations. Typically, a user will experience reduced performance over time due to increased ECC activities as particles build-up on the optics. At some point, the drive will fail due to excessive contamination. We've taken a number of steps with the XM-3300 Series to prevent contamination and ultimately improve reliability while at the same time ensuring high performance."
The drive comes in two models, the XM-3301B for installation in computer systems and the TXM-3301A, an external plug-and-play subsystem. Both models are available with installation kits for IBM PC AT, PS/2 and Macintosh computers and compatibles.
The XM-3301B measures 1.63(H) x 5.75(W) x 8.0 (D) inches and weighs 2.4 pounds. It can operate in positions ranging from horizontal to vertical and features integrated audio capabilities.
Like the XM-3301B, the TXM-3301A external CD-ROM subsystem can operate in a variety of orientations: vertical, horizontal and diagonal. Installation kits for IBM PC AT, PS/2 and Macintosh computers and compatibles include all required connecting hardware and driver software. The subsystem measures 2.75 (H) x 8.0 (W) x 11.0(D) and weighs only 9.25 pounds.
The suggested list price on the TXM-3301A with an installation kit for the IBM PC is $950. The suggested list price for a TXM-3301A with an installation kit for the Macintosh computer is $895. The TXM-3301A with installation kit is available beginning July 1991.
