Abstract: LOADING AND UNLOADING MECHANISM FOR FLEXIBLE MAGNETIC DISKS Mechanism for loading and unloading flexible disks contained in protective envelopes into and from a data recording and reading device for the disks which holds the disks vertically between a drive element and an arbor rotatable on horizontal axes. The mechanism comprises a bin located on top of the recording and reading unit and having a hopper section and a stacker section. Rotatable pick and feed rolls feed a disk in its protective envelope out of the hopper section and downwardly into the recording and reading unit; and, after information has been either read from or recorded on the disk, vertically movable lifter fingers move the disk and protective envelope upwardly to the feed roll which transfers the disk in its envelope into the stacker section of the bin.

Abstract: RECORDING APPARATUS FOR MAGNETIC DISKS USING BOTH SIDES OF THE DISK Magnetic disk recording apparatus including a pair of magnetic transducers contacting the opposite sides of a magnetic disk and each carried by a swingable arm. The arms are interconnected together so that the swinging movement of one of the arms is transmitted to the other arm to cause an opposite swinging movement of the other arm for simultaneously moving the transducers away from the magnetic disk. An electromagnet actuates one of the arms so as to thereby also move the other arm.
