Abstract: The data storage mechanism employs a thin, flexible disk having magnetic recording surfaces on both sides and disposed in a carrying envelope. The envelope has an elongate slot in both thicknesses to permit magnetic read/write heads to make contact with magnetic disk surfaces. A pair of pressure pads are disposed on both sides of the envelope, laterally and equally spaced from the read/write head on each side of the envelope; and the pads hold the disk substantially fixed in the direction extending axially of the disk. An eccentric carries the read/write heads so as to swing the heads about a propelling screw therefor and cause one or the other of the read/write heads to move into contact with a magnetic surface of the disk.
