An exemplary embodiment provides for a cable connection apparatus wherein a connector is mounted on a disk drive chassis, or a sub-assembly attachable to a chassis, such that a cable that connects to the connector will do so along an axis parallel to the chassis or subassembly that the connector is coupled to as opposed to a more typical perpendicular coupling. As a result, the cable will not stick straight out from the back of the drive and the drive footprint is also reduced.

A method and apparatus is provided to protect head elements on a head of a head guide assembly, having a magnetic tape, and a leader coupled to the magnetic tape at a first end, such that the height of the leader is less than the height of the magnetic tape.

System and method for protecting head elements of a tape drive

A magnetic/encoder assembly has a compact design and combines the features of motor, encoder and chuck locating feature within a single motor housing. The motor/encoder includes a DC brushless motor with an inner magnetic rotor. The motor windings and the commutation electronics are mounted towards the bottom side of a printed circuit board. The rotor of the motor is extended above the surface of the printed circuit board. The extended rotor provides a precision seat for the magnetic wheel with multiple poles. The top surface of the printed circuit board mounts the sensor for the encoder. The extension of the rotor provides the precision mounting surface of the cartridge driving chuck.

Motor/encoder assembly for tape drives

A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. A brake member of the magnetic cartridge is provided with a brake gear and is movable up and down between an operative position and a retracted position. The reel is provided with a reel gear which is brought into mesh with a drive gear of a tape drive mechanism and a through hole through which a push rod extending from a brake release member projects to be brought into abutment against the drive gear of the tape drive mechanism so that the brake release member moves the brake member to the retracted position. The through hole opens in an area which is slightly wider than tips of teeth of the reel gear, wherein the area includes a pair of opposed flanks of the reel gear which form a valley.

A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. The reel has a reel hub in the form of a cylindrical member which has a bottom wall and is provided with an opening and a stopper gear formed on the bottom wall. A brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear is brought into engagement with the stopper gear to prevent rotation of the reel and a retracted position where the brake gear is disengaged from the stopper gear to permit rotation of the reel. The brake member is normally urged toward the operative position and moved to the retracted position by a pusher member of a tape drive system which acts on the brake member through the opening in the reel hub when the magnetic tape cartridge is loaded in the tape drive system. A continuous wall portion is erected around the opening in the reel hub, and the brake member includes a horizontal portion and a continuous skirt portion which extends downward from the horizontal portion and is in contact with the continuous wall portion of the reel hub to close the opening together with the horizontal portion. The brake member is moved between the operative position and the retracted position with the skirt portion kept in contact with the continuous wall portion of the reel hub.

A tape drive having a cartridge receiving area for receiving a cartridge containing a recording medium on a supply reel is disclosed. The tape drive has a take-up reel. The take-up reel includes a take-up rotatably mounted to the tape drive and a pair of flanges mounted on either side of the take-up hub. A magnetic read/write head is disposed between the cartridge receiving area and the take-up reel. A pair of fixed guide assemblies is disposed symmetrically about the magnetic read/write head. Each of the fixed guide assemblies has a fixed guide mount fixed to the tape drive, a fixed guide attached to a top of the fixed guide mount, and a spring/pressure pad having at least one pressure pad mounted to the fixed guide, wherein the pressure pad applies pressure to a top edge of the recording medium when the tape drive is operational. The tape drive also has a forward guide roller and a rearward guide roller disposed symmetrically about the magnetic read/write head. The forward guide roller is located between the cartridge receiving area and the one of the pair of fixed guide assemblies and the rearward guide roller is located between the take-up reel and the other of the fixed guide assemblies. Each of the forward guide roller and rearward guide roller includes a shaft mounted to the tape drive and a rotor disposed about the shaft.

Tape path for a cartridge tape drive

A magnetic tape cartridge has a thin cartridge casing having flat upper and lower surfaces and a single reel around which a magnetic tape is wound. Projections are provided on at least three places of the lower surfaces of the cartridge casing near the leading edge and the trailing edge of the cartridge casing and recesses, which can engage with the projections, are provided on the upper surface of the cartridge casing so that, when a plurality of the magnetic tape cartridges are stacked, the projections and the recesses of the cartridge casings of magnetic tape cartridges are engaged with each other, whereby the magnetic tape cartridges are prevented from being displaced with respect to each other when they are stacked and the sliding resistance when the magnetic tape cartridge is inserted into a recording and reproducing apparatus is reduced.

Magnetic tape cartridge having projections

A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation. A slide door for opening and closing a tape outlet opening is mounted on the cartridge casing to be linearly slidable along a door passage between a closing position where it closes the tape outlet opening and an opening position where it opens the tape outlet opening. A door spring for urging the slide door toward the closing position and holding the same in the closing position is disposed on the door passage.

A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. A brake device including a brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear prevents rotation of the reel and a retracted position where the brake gear permits rotation of the reel. The reel is provided with a through hole through which a push rod extending from the brake release member projects to be brought into abutment against the drive gear of the tape drive mechanism so that the brake release member moves the brake member to the retracted position. The through hole and the push rod are in contact with each other by way of fine protrusions formed at the push rod or the through hole.
