A magnetic tape drive in which a tape cartridge is endwise loaded and thereafter minutely moved into a precision alignment position with respect to a read/write head. The drive has a support frame with a front panel and an elongate tray dimensioned to have the cartridge inserted endwise thereon. The tray is supported by the frame for longitudinal sliding movement from a retracted position in which the tray is contained within the frame to an extended position in which a portion of the tray extends through a slot in the front panel. A mechanism is provided for opening the access door of the cartridge while the cartridge is supported on the tray and the tray is being moved from its extended position to it retracted position. Another mechanism is provided for simultaneously moving the head and a capstan drive into engagement with the cartridge once it has been fully inserted and for also moving clamp mechanisms against the bottom plate of the cartridge to minutely move the cartridge against adjustable reference location pins.

DETAILED DESCRIPTION Accordingly, it is the primary object of the present invention to provide an improved cartridge tape drive.
Another object of the present invention is to provide an improved tape drive which will fit within the industry three and one-quarter inch by five and three-quarter inch by eight inch form factor for floppy disk drives while accommodating endwise loading of a standard cartridge defined by ANSI standard X3.
55-1977.
Another object of the present invention is to provide a cartridge tape drive of the aforementioned type having an improved mechanism for aligning the cartridge with respect to the magnetic head.
Another object of the present invention is to provide a cartridge tape drive of the aforementioned type in which movement of a single actuator accomplishes engagement of the magnetic head and capstan drive with the tape cartridge and movement of the tape cartridge into precise alignment with the magnetic head.
Another object of the present invention is to provide a cartridge tape drive of the aforementioned type in which the azimuth and zenith relationships between the tape cartridge and magnetic head may be finely adjusted.
Another object of the present invention is to provide a cartridge tape drive of the aforementioned type having a frame structure which provides the entire mechanical support.
Still another object of the present invention is to provide a cartridge tape drive of the aforementioned type which can operate in three different orientations.
Still another object of the present invention is to provide a cartridge tape drive of the aforementioned type in which the cartridge can only be fully loaded if the cartridge is correctly oriented with respect to the drive.
Yet another object of the present invention is to provide a cartridge tape drive of the aforementioned type in which the cartridge support tray automatically slides to its extended position when the cartridge is removed from the drive to thereby prevent damage to the tape access door opening mechanism which might otherwise occur during cartridge re-load
