Data transfer apparatus for use with a magnetic disk cartridge

摘要

A flexible magnetic disk, rotatably housed in an apertured envelope to make up a disk cartridge, is loaded through an entrance slot in the housing of the apparatus to a preassigned position for data transfer with a pair of transducer heads on its opposite sides. Upon subsequent manipulation of a clamp know, one of the transducer heads is sprung into forced contact with the other transducer head via the magnetic disk therebetween. In order to avoid the direct contact of the two transducer heads as a result of the user's tampering with the clamp knob when the disk cartridge is not loaded in the apparatus, a head control mechanism is provided for holding the transducer heads away from each other when the disk cartridge is not loaded, even if the clamp assembly is then actuated inadvertently. The head control mechanism allows the one transducer head to travel toward the other for the establishment of data transfer contact with the magnetic disk only when the clamp knob is actuated following the insertion of the disk cartridge in the entrance slot.
