Summary

Description
English: Qume 8 inch Floppy Disk Drive. Announced October 1978.

Michalopoulos, D. A. (1978-12). "New Products". Computer 11 (12): 81.

A new dual-sided, double-density diskette drive reduces media wear to far below industry norms, according to Qume Corporation. The company has obtained an exclusive right to manufacture the drive for the North American and European markets from Y. E. Data, Japan's leading supplier of floppy disk drives.

[Six paragraphs of press release omitted.]

The DataTrak 8 stores 1.6M bytes of unformatted data and 1.2M bytes of IBM-formatted data. Track-to-track access time is three msecs, average access time is 91 msecs, and settling time is 15 msecs. The drive's data transfer rate is 500K bits per second. Standard options include file protection, programmable door lock, and activity light. The drive is compatible with all existing drives, including IBM.

The DataTrack 8 is immediately available and is priced at $755 in OEM quantities of 1-24.
