ABSTRACT:
A machine operative to sequentially pull jacketed flexible magnetic disks (which may be termed "diskettes") into a data transferring position in the machine directly from a carriage or from a magazine carried by the carriage and to return the diskette back into the carriage or magazine. The jackets of the diskettes are square; and the carriage and the magazine are provided with flat sided, flat bottomed store grooves for holding such diskettes. The machine is likewise provided with a diskette receptor groove having flat sides and a flat bottom and holding a diskette in its data transferring position in the machine. The flat sided and bottomed grooves cooperating with the square diskette jackets prevent a binding or jamming of the diskettes as they are moved from the carriage or magazine into the machine and back again, and the movement of a diskette is only partially out of a store groove in the carriage or magazine so that the diskette is certain to be moved completely back into its original store groove in the carriage or magazine after a data transfer has taken place and so that the machine is shortened to this extent. The carriage has a few store grooves for a few diskettes desired to be individually used, and the magazine has a greater number of diskette store grooves for a group of diskettes desired to be used together.
