Abstract: DRIVE MACHINE MOVING MAGNETIC DISKS ONLY PARTIALLY THEREIN FOR DATA TRANSFER 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.

Abstract: A computer system having a removable hard disk drive is disclosed. The interposer card is modified to receive a docking bay which receives a cartridge which contains a hard disk drive. The docking bay includes the male portion of a zero insertion force connector and a first circuit board to which connects to the interposer card of the computer. The first circuit board also includes circuit paths between the male portion of the zero insertion force connector and the end which connects to the interposer card of the computer. The first circuit card also includes circuitry which allows "hot plugging" of the hard disk drive to the bus of the computer and which also acts as a lockout to prevent writing to the removable hard disk drive until after the computer system has been rebooted. The docking bay also includes a spring mechanism for ejecting the cartridge. A finger lever holds the cartridge in place and can be lifted to eject the cartridge. A hard disk drive is placed within a cartridge which includes a second printed circuit board. Attached to the second printed circuit board is the female portion of a zero insertion force connector.
