Abstract: The invention pertains to developments for manipulating and referencing a magnetic tape cassette in a magnetic tape device involving loading, read/write and tape drive operation, and unloading. To load and unload the tape cassette, a tape drive bridge on which the magnetic head is mounted is disposed in a standby position out of the way of the path of movement of the tape cassette into and out of the recorder housing. A gripper disposed for longitudinal movement on a gear rack in the recorder housing, is arranged to bite the cassette to automatically carry the cassette inwardly to its fully loaded position and then again move the cassette outwardly to its unloaded position. A lever arm arrangement is provided to appropriately open the dust cover door on the tape cassette, to expose the cassette tape for operational engagement by the magnetic head, as the tape cassette approaches its fully loaded position within the recorder housing. The gear rack serves to activate this lever arm for opening the dust cover. The tape cassette is preferably loaded endwise into the recorder housing, and when the cassette has been fully loaded in the recorder housing, the tape drive bridge carrying the magnetic head is rotated in all three axes from its standby position to its running position. In its running position, the tape drive bridge locks the tape cassette to it, by gripping the cassette at three reference areas on the bridge. A manual eject mechanism utilizes an exposed button on the recorder housing which is manipulated by the operator to causing unloading of a stranded tape cassette, should the electrical system not work.

Abstract: A motor mount arrangement for a capstan drive motor mounted to a tape drive bridge (46) in a magnetic tape recorder, the bridge arranged for movement toward and away from a magnetic tape cassette loaded in the recorder, the motor support arrangement configured as a circular aperture (100) through the bridge partly defined by an arcuate flexible finger portion (96), and diametrically opposed dimples (116,118), at least one of which is arranged in the flexible finger portion (96). The motor provides diametrically opposed protrusions (110,112) which interfit into the dimples allowing pivoting of the motor about an axis defined between the two protrusions. The flexible finger portion (96) is displaceable radially outwardly from the motor held thereby to remove or install the motor into the bridge. The flexible finger portion is backed-up by a plastic bushing (106) compressed against a relatively rigid portion which retains the motor protrusions within the recesses and also dampens vibrations to or from the motor.

Abstract: A drive unit for driving magnetic tape held within a tape cartridge, the tape cartridge engaged to the drive unit in abutting fashion. The drive unit provides an elastomeric drive belt which surrounds a drive pulley, a tensioning pulley and an engagement pulley, the engagement pulley resiliently urging the drive belt against a cartridge roller located within the cartridge which progresses the magnetic tape within the cartridge. The drive pulley is driven directly by a motor which progresses the belt around the three rotating pulleys. The arrangement eliminates the need for a separate friction roller arranged above the drive belt by using the drive belt itself to drive the cartridge roller.

Abstract: A method and system are disclosed for improved edge detection on tapes. By use of a nominal tape having a 100% output, a write head writes with a given write current onto the nominal tape and the output level is read with a read head during a calibration procedure in order to determine a reference level for the 100% nominal tape. Thereafter, when an actual tape is being used, by use of the same write current, a signal is written on the actual tape and is subsequently read to create a read output. That read output is compared to the reference level output derived during the calibration to create a correction factor. The correction factor is then employed to correct a trigger point utilized during a subsequent tape edge determination.

Abstract: 5 n7 A device for positioning a magnetic head to an operative position relative to a selected track of a multi-track magnetic tape in a magnetic tape write/read device. A magnetic head is disposed at one end of a magnetic head carrier while the opposite end of the head carrier is axially movable along a shaft fixed to the tape recorder housing frame. An inchworm-type servo system is provided which has two clamping devices arranged stacked axially along the shaft and a positioning device connected between the two clamping devices which can be altered in length to move the clamping devices toward or away from each other. By alternatingly clamping the two clamping devices to the shaft and altering the distance between the two clamping devices in coordination, the servo system can crawl up and down the shaft to position the magnetic head. In another mode of operation, the clamp which mounts the head carrier is left unclamped with respect to the shaft, the opposite clamping device is clamped with respect to the shaft, and the extending device is allowed to expand or contract over its operable range to minutely position the head with respect to the tape. In the preferred embodiment, the clamping devices and the extending devices are piezoelectric elements which receive a voltage potential to correspondingly expand or contract. By contracting the clamping devices are actuated to clamp tightly to the shaft to prevent axial movement.
