Diskette Interfaced Backup/Restore and Data Transfer System

      Disclosed is a method which attaches high capacity tape data
storage to any workstation without any electrical connections.
Shareable between multiple workstations.

      The portable backup/restore data transfer system is a self
contained tape backup and retrieval system which contains a tape
drive mechanism for data storage, interface and control logic and a
specially designed diskette interface adapter that can be inserted
into any standard PC or workstation diskette drive (Fig. 1).  A
specially designed diskette adapter, containing a mating R/W magnetic
head assembly and diskette physical form factor, plugs directly into
the workstation diskette drive.  A small cable protrudes back of the
diskette adapter and plugs directly into the tape backup unit.
Diskette adapters are available for all sizes of diskette drive media
that the PCs/workstations may contain and are interchangeable with
the backup/restore system.  Power is obtained from any standard AC
wall outlet or from an optional rechargeable battery adding to the
portability of the unit.

      Special software is installed on the PC/workstation which
controls the data transfer system via the diskette interface.
Control blocks are mixed with data blocks to allow a bi-directional
flow of information.  For design simplicity and reduced diskette
drive wear, all data is read and written to track 0 totally
eliminating any drive head movement.  In this manner, the tape drive
emulates a very large track 0 with megabytes of storage available
(based on the tape size in use).

Features - Due to ease of use, high portability, and with a variety
of diskette interfaces available, the backup/restore unit can be
shared among many work stations.  Sensitive workstation data,
retained on miniature tape media, can be maintained and controlled by
the workstation owner for security purposes.  Interfacing to
different workstations employing different operating systems is
totally transparent, providing the appropriate backup software is
used with each different operating system.

Some of the important features of this system are:
  o  Transfer system requires no electrical connection to the
      workstation.
  o  Attachment is as simple as inserting a diskette.  (Using the
      contained battery pack, no wired connections of any type are
      required.)
  o  Any type of workstation can be used independent of the hardware
      design.
  o  Appropriate SW would be available for any desired operating
      system.
  o  Diskette interfaces are available for all forms of storage
media,
      (360K, 1.2M, 720K, 1.44M, 2.88M etc.).
  o  Future new drive media adapter interfaces can be provided as...
