Abstract: In accordance with embodiments of the present disclosure, a sequential storage media drive may include a first reel for rotatably winding sequential storage media tape from an opposing second reel of a data cartridge, an enclosure for housing the first reel and housing the data cartridge when the data cartridge is inserted into the sequential storage media drive and an access door mechanically coupled to the enclosure, the access door configured to be translated from a closed position to an open position to allow a user to access the first reel from an exterior of the enclosure in the event the data cartridge of the sequential storage media tape becomes lodged in the sequential storage media drive.

Abstract: This invention relates to a tape applicator or tape head formed from a combination of two separated apparatuses namely a detachable unit containing a front portion of the tape applicator and a stationary unit containing a rear portion of the applicator with snap-on engagement there between to obtain the interactive motion of a conventional tape applicator i.e. the present invention separates a conventional tape applicator into two separate portions which results in the ability to quickly change tapes and reduces safety hazards.

Abstract: A recording tape cartridge which can prevent positional offset of a case with respect to a cartridge accommodating device. Accompanying operation of loading the cartridge in an arrow A direction into a drive device, a door is moved to a side of opening an opening while an operation projection is engaged by an engagement projection. At this time, a pushing/engaging member of the drive device enters into a cell retention notch, and pushes a push surface and engages with an engagement surface. In this way, at the case, a moment in an arrow E direction around a region of engagement is offset, and the case is prevented from being coming out from the drive device. An inclined surface permits advance and withdrawal of the pushing/engaging member into and from the notch.
