摘要： A rotary head device for a recording and reproducing apparatus includes a rotary drum (1) and a stationary drum (2). The rotary drum has a guide surface (5) formed of a conical surface coaxial with the axis of rotation of the rotary drum and wound with a magnetic tape (7). A head unit (12) is mounted on the rotary drum to be rotatable integrally therewith. The head unit includes two head elements (4, 6) facing each other, for scanning the tape wound on the guide surface, while the tape is being interposed between the head elements, as the rotary drum rotates.

摘要： A head drum assembly of a tape recorder in which an inner race and an outer race of an upper bearing are press-fitted onto a shaft and a rotary drum, respectively, thereby applying a preload. A resilient body, such as a compressed coil spring, is disposed between a lower bearing disposed between the rotary drum and the shaft and a stationary drum. The resilient body upwardly presses the inner race of the lower bearing, thereby applying a preload. Accordingly, the head drum assembly of the tape recorder provides enhanced assembling efficiency and reduced manufacturing costs.

摘要： To control operations of an arcuate scanning head assembly, servo signals are written in one or more designated servo regions along a recording tape, for example along one or both edges of the recording area on the tape. To minimize the space occupied by the servo signals, the servo signals are always written with an azimuth that is substantially parallel to the longitudinal axis of the tape. In the preferred embodiment, servo signals aligned with adjacent tracks are written at two different positions within a servo region. As a read head passes over a track and the servo region, the head should overlap the servo signal aligned with that track and a portion of the servo signal aligned with the adjacent track. A control system samples the signal from the read head in a first time window corresponding to passage of the head across a burst aligned with the track and in a second time window corresponding to passage of the head across a burst aligned with the adjacent track. The system controls one or more parameters relating to the scanning operation as a function of a relationship of the two sampled amplitudes.
摘要翻译：为了控制弧形扫描头组件的操作，伺服信号沿着记录带写入一个或多个指定的伺服区域中，例如沿着磁带上的记录区域的一个或两个边缘。为了最小化伺服信号占用的空间，伺服信号总是以与磁带的纵向轴线基本平行的方位角写入。在优选实施例中，与相邻轨道对准的伺服信号被写入伺服区域内的两个不同位置。当读取头经过轨道和伺服区域时，头部应重叠与该轨道对准的伺服信号，并且伺服信号的一部分与相邻轨道对齐。控制系统在第一时间窗口中对来自读取头的信号进行采样，该第一时间窗口对应于穿过与轨道对准的突发的头部的通过，以及对应于头部跨越与相邻轨道对准的突发的通过的第二时间窗口。系统控制与扫描操作有关的一个或多个参数作为两个采样振幅的关系的函数。

Also, at least one read/write head is included and is coupled to receive an amplifier output from the amplifier and return a read data signal to the amplifier. Also disclosed is a method for reading and writing data to a tape storage medium. The method may include the steps of: providing a rotating head drum adjacent to the tape, the head drum including at least one read/write head and an amplifier coupled to the head; encoding preamplifier control signals and the data in a synchronous signal; transmitting the synchronous signal through a rotating transformer to the head drum; transmitting a clock signal through the rotating transformer; transmitting a power to the preamplifier; and decoding the synchronous signal so that the preamplifier is directed to write the data to the tape.

摘要： In an arcuate scanner, a read head senses passage over a reference stripe recorded on a moving recording tape. Detection and logic circuitry respond to the read head signal to detect the reference stripe and determine an angular position of the read head with respect to an index associated with the arcuate scanner head assembly. Timing operations of the arcuate scanner and alignment of the arcuate scanner head assembly with regard to an information recording region on the tape are controlled in reference to the detection of the reference stripe.

摘要： PURPOSE:To attain high-density recording and to record a large amount of voices with a small quantity of magnetic tape for easy transportation, storage and control, by providing plural magnetic heads on a disk to perform the recording and reproduction in an arc from and vertically to the moving direction of the tape. CONSTITUTION:Three magnetic heads 10 are set on a disk 9 and revolved at a fixed speed to move a magnetic tape 8 at a low speed on one or plural arc-shaped tracks 13. Thus those tracks on the tape 8 are recorded consecutively with spaces between several hundred mum and several mum. At the same time, the control signal of a control signal device 11 is recorded at the upper or lower part of a track 12. Then a recording track 13 is controlled to reduce voices with high density. In a reproduction mode, the control signal of the track 12 is detected by the device 11 and the voice data is detected out of the track 13 by the head 10 to obtain voices.
