ABSTRACT:
Apparatus and method wherein a credit card sized memory card having a magnetic storage medium thereon can be inserted into an operative position adjacent to a read/write head, and the card and head can be moved relative to each other to permit the head to read data from or to write data on the magnetic medium of the memory card. In a first embodiment, a disk form is provided like a hard disk but with a cut out portion or opening therein into which the memory card is insertable. The disk form can then be rotated so that the magnetic medium on the card can be moved past the read/write head movable radially of the central axis of the disk form. In another embodiment the memory card is movable into a fixed operative position adjacent to a read/write head and the head is movable radially as well as circumferentially arc so that the head and memory card are movable relative to each other in two degrees of freedom.
