    摘要： A head drum assembly (200) of a tape recorder in which an inner race and an outer race of an upper bearing (250) are press-fitted onto a shaft (240) and a rotary drum (210), respectively, thereby applying a preload, and comprises preload means including a resilient body (270) such as a compressed coil spring that is disposed between a lower bearing (260) disposed between the rotary drum and the shaft and a stationary drum (220), the resilient body for upwardly pressing the inner race of the lower bearing, thereby applying a preload. Accordingly, the head drum assembly (200) of the tape recorder provides enhanced assembling efficiency and reduced manufacturing costs.

    摘要： A multi-channel head position control apparatus and a method of controlling the position of the multi-channel head in which even if the width of a tape-like recording medium is changed, each of unit recording heads constituting a multi-channel head can be aligned with corresponding track centers. The multi-channel head having a plurality of unit recording heads arrayed in the longitudinal direction is disposed so that the alignment direction of the unit recording heads forms an azimuth angle relative to the running direction of the tape-like recording medium. The position of the multi-channel head is controlled by a supporting section in accordance with a control signal recorded on the tape-like recording medium and detected by a detecting section so that the alignment between each of the unit recording heads and corresponding track center is maintained.

    摘要： Described herein is a rotary head cylinder assembly including a fixed lower cylinder for guiding travel of a magnetic tape, an upper cylinder rotatably mounted on the lower cylinder and provided with a number of magnetic heads, and a circuit board fixedly mounted on the upper cylinder and supporting thereon amplifiers in positions in close proximity to the respective magnetic heads. The circuit board is provided with notched portions at the outer periphery to permit direct access to screws for adjusting the height of the magnetic heads as well as to holes for adjusting the position of the magnetic heads from above the top side of the cylinder, while preventing interference by undesirable signals.
