Hitachi America announces next generation, 2.6 gigabyte magneto-optic drives; backward-compatible with all previous 5.25-inch multifunction products, new 4X technology drives conform to proposed ISO standard.



BRISBANE, Calif.--(BUSINESS WIRE)--Nov. 1, 1995--Hitachi America Ltd.'s computer division today announced its next generation, 5.25-inch magneto-optic drives.

The 172 Series optical drives support 4X storage data densities, using 2.6 gigabyte (GB) rewritable optical media See rewritable optical disc. , as defined in the proposed ISO (1) See ISO speed.

(2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI.
 standard. Hitachi's third-generation of multifunction optical drive technology also is read/write compatible with 2 GB, 1.3 GB and 650 MB magneto-optic media.

The new drives, available in December in sample quantities and in production quantities in the first quarter of 1996, provide high-capacity, removable optical storage capability for a wide range of workstation and personal computer applications, including computer-aided design computer-aided design (CAD) or computer-aided design and drafting (CADD), form of automation that helps designers prepare drawings, specifications, parts lists, and other design-related elements using special graphics- and calculations-intensive  and engineering, database back-up and restore, geographic and medical imaging, electronic publishing An umbrella term for non-paper publishing, which includes publishing online or on media such as CDs and DVDs.  and pre-press applications.

Optical libraries based on the new drives, with capacities from 125 GB to 501 GB, are ideally suited for hierarchical storage management See HSM.  and multimedia (combined image and code data) database applications in client/server and networked PC environments.

Hitachi's 172 Series magneto-optic drives utilize proven technologies, first implemented in the company's previous generation 2 GB drives, including Zoned Constant Angular Velocity See CAV.  (ZCAV See CAV. ), mark-edge recording and 1-7 encoding, as well as a new 685 nm wavelength laser for data recording.

This combination of proven technologies and investment in engineering over three generations of MO drive technology provides high reliability (80,000 hour MTBF (Mean Time Between Failure) The average time a component works without failure. It is the number of failures divided by the hours under observation.

Hitachi has implemented one pass write capability to improve performance. The drives also utilize the SCSI-2 interface and have a 1 MB buffer memory to support the demanding performance requirements of graphics-oriented and network storage applications.

In particular, this speeds access to complex databases (such as still and moving images with computer data) throughout a network.

Reseller, OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and  Targets

Hitachi America will market the new drives through its in-place U.S. distribution network, and through direct sales to large OEM customers. The half-height form factor OD172, suitable for installation into desktop computers and workstations, also will be supported for sale to manufacturers of optical libraries.

The OU172 model of the drive is designed for use as a stand-alone unit, complete with self-contained power supply and power cable.

The full-height OL-F172 library drive will be integrated into two optical library storage systems for sale to resellers and OEMs. These libraries feature average disk to drive mount times of 8.0 seconds or less.

The OL172-48 supports one to four drives and 48 to 60 optical disks. The OL172-180 has equivalent drive capacity and supports 180 to 192 optical disks. (Note: with maximum disk loading Disk Loading is the pressure (weight force divided by disk area) maintained over the swept area of a helicopter's rotor. A heavy helicopter with short rotors will have more disk loading than a light helicopter with long rotors.

A low disk loading allows better autorotation.
, each library can support up to two drives.)

Additionally, up to three libraries can be daisy-chain connected to provide total capacity of up to 1.5 terabytes (using the OL172-180) operating through a single SCSI-2 controller.

Pricing, Availability

Sample quantities of the drive family will be available in December, for evaluation by qualified resellers and OEMs. Pricing for individual sample units is $2,600 for the half-height, drive-bay installable OD172 and $3,100 for the stand-alone OU172.

Evaluation units of the optical library systems will be available in the first quarter of 1996.

Suppliers of 2.6 GB capacity media, conforming to the proposed ISO standard and tested on the new Hitachi drives, include Maxell Corp., Mitsubishi Chemical Corp., Sony Corp., Tosoh Corp. and 3M.

With the introduction of the 172 Series drives, Hitachi's 5.25-inch multifunction optical product line is now synchronized with the roadmap for standard technology development established by OSTA (Optical Storage Technology Association, Cupertino, CA, www.osta.org) A membership organization composed of major optical drive manufacturers. Established in 1992, its purpose is to endorse standards and promote the use of optical media in computing.  (Optical Storage Technology Association) and supported by international standards bodies Following are some of the standards bodies defined in this database.

Hitachi expects to continue its worldwide leadership in optical storage technologies in conformance with standards set by these informal and officially sanctioned organizations.
