摘要： The present disclosure generally relates to a tape drive including a tape head. The tape head comprises at least one same gap verify (SGV) module comprising a plurality of write transducer and read transducer pairs disposed on a substrate. Each pair comprises a null shield disposed between the write transducer and the read transducer. One or more of a position between the write transducer and the read transducer of each pair, a width, a height, a thickness, and a permeability of the null shield is adjusted to create a null region, and the read transducer is disposed in the null region. The SGV module is configured to write data to a tape using the write transducer of each pair and read verify the data written on the tape using the read transducer of each pair such that the write transducer and read transducer of each pair are concurrently operable.

摘要： A video cassette recorder includes an arm for connecting an intermediate gear driven by a capstan motor and an idler gear, a reel sensor for recognizing whether a supply reel table rotates or not, and a lever for selectively limiting the shifting movement of the idler gear to the supply reel table. The lever is provided on a deck so as to selectively come into contact with the arm oscillating toward the supply reel table in response to the movement of a sliding plate, or the presence or absence of a record tab on a loaded video cassette tape when the video cassette recorder is in a record mode and to keep a non-contacting status with respect to the arm when the video cassette recorder is in another operating mode.

摘要： A reel table driving device for use in a video cassette recorder comprises a pair of idlers disposed adjacent to a supply reel table and a take-up reel table in order to minimize the travelling distance thereof as a support plate for rotatably holding the idlers is rotated by the conversion of the operating mode, said idlers being constructed of a stepwise relationship with each other so that each reel table generates a sufficient torque during the switching of the operation mode, thereby preventing slackness of a loaded magnetic tape.

摘要： A combination of a tape cassette and a tape drive motor wherein a shaft is connected to a tape reel. A tape reel support is mounted to the housing of the cassette and a tape reel shaft extends through the support. Bearings are carried by the support for rotatably supporting the tape reel shaft and thereby the tape reel on the cassette housing. The motor has a rotor rotatable about an axis with the rotor being loosely mounted in the motor when a cassette is not in the tape drive. In one embodiment of the invention, the rotor carries a magnet which in combination with magnetically attractive material carried by the shaft, operates to connect the rotor to the shaft to effect a driving relationship between the rotor and shaft when the cassette is in the tape drive. The bearings on the cassette for the tape reel shaft served as the sole bearings for the rotor for rotational support when the rotor rotates and drives the shaft and thereby the tape reel. In another embodiment of the invention, one axial end of the rotor is connected to the tape reel shaft and the opposite axial end has a pointed end which engages pivot bearings to render stability to the rotor against possible rotor whip when the rotor is rotating. In this embodiment, the rotor is primarily supported for rotation by the bearings on the cassette and is secondarily supported by the pivot bearings on the motor housing.

摘要： A reel table driving device, for a video cassette recorder, comprises a pulley, a driving gear rotated with the pulley, and a first and a second idle gears rotatably fitted on a post fixed to a bracket pivotably mounted to the deck. The first and the idle gears are frictionally coupled to each other through a friction member. The pulley is provided with a boss tightly fitted on a shaft rotatably held by the deck, the boss having a pair of opposite guide groove axially extending. The driving gear has a pair of protrusions inwardly protruding from an inner surface thereof and is fitted onto the boss of the pulley in such a manner that the protrusions are inserted in the respective guide grooves. The driving gear is movable up and down along the guide grooves and rotated together with the pulley by the interaction of the protrusion and the guide groove. A compressive spring is disposed between the driving gear and the pulley, biasing the driving gear upwardly to thereby allow the driving gear to be engaged with the first idle gear during a fast forward or rewind mode, and a pressing member presses the driving gear downwardly against the compressive spring to thereby allow the driving gear to be engaged with the second idle gear during a play mode.

摘要： In a capstan motor, a gear portion and an FG detection portion are integrally formed of a plastic magnet at mutually different wall thicknesses and they are fixed to the outer circumference of a rotor yoke. The FG detection portion is provided with multipolar magnetization to generate a rotation detection signal with a magnetoresistance element. The gear portion is arranged to transmit the drive force to the outside. The outer diameter of the rotor yoke is different at the gear portion and at the FG detection portion, depending upon the wall thicknesses of the plastic magnet. The outer diameter is set to be greater in the portion corresponding to the FG magnet of the rotor yoke.

摘要： A magnetic tape drive having a motor with a magnetically shielded cavity or hole in one cover of the motor providing additional room for movement of a magnetic head. The cavity eliminates a mechanical interference problem, enabling direct drive of a roller (puck) combined with short overall drive height. In motors having an internal stator, some of the stator poles are eliminated and a magnetically shielded cavity is provided in the area where the stator poles are eliminated. In motors having an external stator, no stator modification is required and a shielded cavity provides access into an open area of the rotor. In addition, for motors having an external stator and sufficient magnetic shielding, a simple hole in one cover of the motor may be sufficient rather than a magnetically shielded cavity.
