ABSTRACT:
An interface system, preferably made in the shape and size of a standard removable magnetic medium, and inserted inside a removable magnetic storage unit such as a floppy disk drive or a tape backup drive, is disclosed. Magnetic communication means on the interface system, placed at a close proximity to the read/write head of the magnetic storage unit, exchange data with the read/write head of the magnetic storage unit. The data protocol is similar to the one used by the magnetic storage unit so that the same standard storage unit can alternatively use both the interface system and the regular magnetic media. Several alternate embodiments of the magnetic communication means of the interface system are disclosed. Data from and to the magnetic communication means may be amplified, shaped, and possibly converted from serial format to parallel format by control circuitry which may be fully integrated inside the interface card. The interface system can interface a computer to virtually any external application system, and it is also usable for data communication between two or more computers.
