Abstract: A media-detection system for a cartridge-receiving device may comprise, according to one embodiment, a cartridge-referencing member mounted to the cartridge-receiving device. The cartridge-referencing member is resiliently displaceable by a data cartridge received in the cartridge-receiving device. A sensor is operatively associated with the cartridge-referencing member. The sensor detecting the data cartridge in the cartridge-receiving device based on the displacement of the cartridge-referencing member.

Abstract: In one embodiment, a load position sensor for a tape drive includes a tape cartridge loading mechanism, a head movable in response to movement in the loading mechanism, and a sensor operatively coupled to the head for sensing a position of the head.

Abstract: A storage system comprises a first plurality of storage cartridges along an accessible side of a path, a second plurality of storage cartridges along a non-accessible side of the path, and a transport device to move the first and second plurality of magazines around the path. The storage system further comprises a controller that determines the location of a particular cartridge and operates the transport device to move the particular cartridge to the accessible side of the path to gain access to the particular cartridge. The controller can also be configured to re-position a movable accessor device along the accessible side of the path to access the particular cartridge. The ability to move the cartridges on both sides of the path can at least double the accessible storage capacity of the system.

Abstract: A media detection system includes a light source mounted within a cartridge receiving chamber defined by a cartridge engaging assembly. A cartridge referencing member has an arm portion mounted to the cartridge engaging assembly and a head portion located within the cartridge receiving chamber at a position adjacent the light source. The cartridge referencing member is deflected by a data cartridge within the cartridge receiving chamber so that when no data cartridge is located within the cartridge receiving member, the cartridge referencing member is not deflected and the cartridge referencing member blocks light from the light source. When a data cartridge is located within the cartridge receiving member, the cartridge referencing member blocks less light from the light source. A detector assembly mounted within the cartridge receiving chamber detects whether light from the light source is blocked or not blocked.

Abstract: A universal cartridge magazine system and method are disclosed for storing cartridge systems. The cartridge magazine system comprising a pivoted member, a flag positioner and a sleeve designed to accept the cartridge system, the sleeve having a first side. The pivoted member has a leg and an arm, the leg having a slanted surface, wherein the pivoted member is designed to allow full insertion of the cartridge system in the sleeve if the cartridge system is inserted in a correct orientation, and wherein the pivoted member prevents full insertion of the cartridge system in the sleeve if the cartridge system is not in the correct orientation.

Abstract: A media-detection system and method for identifying a type of data cartridge. According to one embodiment, the media-detection system comprises at least one indicator arm displaceable by at least one surface feature of the data cartridge as the data cartridge is loaded in a cartridge-receiving device. The media-detection system also comprises at least one sensor detecting the displacement of the at least one indicator arm as the data cartridge is loaded, thereby indicating the type of data cartridge in the cartridge-receiving device.

Abstract: A method for sensing position that comprises generating light, eclipsing the light according to position, sensing the amount of light not eclipsed, and inferring position according to the sensed amount of light.

Abstract: An intrusion monitor for a media storage system. One embodiment of the intrusion monitor comprises a flag operatively associated with at least one storage compartment in the media storage system, the flag moving between a first position and a second position to indicate the state of at least one storage compartment. A sensor provided in the media storage system, the sensor detecting the position of the flag to determine the state of the at least one storage compartment.

Abstract: A write once read many magnetic tape system has a tape cartridge housing a length of magnetic tape adapted to record and store electronic data, and an electronic memory device. A tape drive receives the tape and reads the memory device. The drive is operable only in a write once read many mode in response to information read from the memory device.

Abstract: A split compound gear assembly for a drive loader of the type having an overcentering mechanism with a drive loader actuator shaft. The split compound gear assembly may comprise a drive gear operably connected to a motor, and a first compound gear engaging the drive gear. The assembly also comprises a split compound gear engaging the first compound gear which allows the overcentering mechanism to quickly snap closed. The split compound gear includes an inner member including an inner, smaller gear which is freely rotatable within an outer member including an outer, larger gear. The split compound gear assembly may also include a sector gear which engages the inner gear of the split compound gear and rotates the drive loader actuator shaft.

Abstract: A system for testing and cleaning a removable media drive such as a tape drive includes a utility cartridge and computer readable program code to initiate utility operations. The utility cartridge comprises computer readable magnetic storage media for performing testing operations thereon and non-magnetic cleaning media for cleaning the drive head.

Abstract: An integral tape path assembly (110) includes a head subassembly (112), a buffer/guide subassembly (114) and a spaced sensor/guide subassembly (116), all mounted to a common tape path plate (118). The buffer/guide subassembly includes a buffer arm (126) which pivots about an axis shared by a fixed guide (128). A Hall-effect position sensor (186) can be mechanically calibrated via an aperture (142) in a housing (132). The speed sensor/guide subassembly includes a roller (148) which serves to guide the tape on the take-up side of the tape drive system and to drive a shaft (152) holding a speed indicator (156) for a speed sensor (158). The speed sensor/guide subassembly includes a fixed-orientation washer (206) for urging the tape against an upper flange (208) of the roller. The washer is off-center sprung to counter distorting forces engendered by the tape as it engages the roller.

Abstract: A device which may be incorporated in a conventional magnetic tape transport prevents adhesion between the magnetic tape and elements of the tape transport such as the magnetic head and the tape cleaner. When the tape speed falls below a preselected minimum, the device mechanically displaces the magnetic tape without significant wear on the tape.
