摘要： A media element library includes a magazine of media element storage locations comprising at least one cell adjacent to an opening in the housing. The cell may be moveable so as to extend toward the opening in the housing of the media element library, thereby facilitating user access to a media element stored in the moveable cell.

摘要： 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.

摘要： A magnetic head is attached to a hollow carriage which surrounds a hollow cylindrical positioner post rigidly secured at one end to a frame element of a tape drive. Precision ball bearings mounted to the carriage engage the outer surface of the cylindrical positioner post at longitudinally and circumferentially spaced locations. A positioner shaft extends through the positioner post and a tracking nut in one end of the carriage is screwed over a threaded segment of the shaft. A pin extends from the carriage and is longitudinally slidable in a recess in an anti-rotation block mounted on the frame element. A stepper motor can drive the shaft to reciprocate the carriage toward and away from the frame element thereby moving the head traversely with respect to a length of magnetic tape. An adjustable stop on the post limits movement of the carriage toward the frame element.

摘要： A drive which permits endwise loading of the ANSI standard one-quarter inch tape cartridge in an enclosure having a width of approximately five and three-quarter inches. The drive has a mechanism for partially opening the tape access door of the cartridge upon insertion thereof so that the door pivots clear of a read/write head. Another mechanism is provided for thereafter operatively engaging and disengaging the read/write head with a length of tape in the cartridge.

摘要： A drive for a tape cartridge having an access door along one side edge thereof. The drive includes a housing having a front panel and an elongate tray dimensioned to have the cartridge inserted endwise thereon. The tray is supported within the housing for longitudinal movement from a retracted position in which the tray is substantially contained within the housing to an extended position in which a portion of the tray extends through a slot in the front panel of the housing. 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 its retracted position. Another mechanism is provided for moving a read/write head and a capstan drive within the housing between operative engagement and disengagement with the cartridge after the cartridge has been inserted onto the tray and the tray has been moved to its retracted position.

摘要： Supply and take-up reels are mounted above a horizontal base for selective powered rotation about respective vertical axes. Vertical guide surfaces and a cover panel define an air tight continuous flowpath extending between the peripheries of the reels past a read/write head. A blower mounted in a hood structure beneath the base sucks air through the flowpath and through a perforated center spool of the take-up reel. A river of air thus pulls and guides the free end portion of the magnetic tape from the supply reel to the take-up reel as the supply reel is rotated by a drive motor to unwind the tape therefrom. The supply hub is adapted to automatically center the supply reel thereon. The supply hub further includes a plurality of annularly spaced reel engaging pawls mounted in, and normally retracted into the hub, and an over-center actuating means for selectively extending the pawls through differential rotation of a pair of separate rotors included in the hub.
摘要翻译： 供应和收卷盘安装在水平底座上方，用于围绕各自的垂直轴进行选择性动力旋转。 垂直的引导表面和盖板限定了一个气密连续的流动路径，其延伸在卷轴的周边经过读/写头之后。 安装在基座下方的发动机罩结构中的鼓风机通过流路吸入空气，并通过卷取卷轴的穿孔中心卷轴吸入。 因此，当供应卷轴由驱动马达旋转以使卷筒退绕时，空气河由此拉动并将磁带的自由端部从供带盘导引到卷取卷轴。 供应轮毂适于使供应卷轴自动居中。 供应轮毂还包括多个环形间隔开的卷轴接合爪，其安装在并且通常缩回到轮毂中，以及用于通过包括在轮毂中的一对单独的转子的差速旋转来选择性地延伸棘爪的过中心致动装置。
