摘要： A drum servo system used in an apparatus reproducing an audio signal in the form of digital data and a video signal which are recorded according to a signal in the video signal asynchronizing with the audio signal comprises a drum with a reproducing head, detecting means for detecting a velocity of rotation of the drum during recording represented by a sampling number per second of the digital data, and rotating means for rotating the drum based on the detected velocity. This correction enables the reproduced audio and video signals to become closer to the original audio and video signals, especially enables the reproduced audio signal to become in correct tune.
摘要翻译：一种滚筒伺服系统，其具有旋转控制装置，该旋转控制装置用于根据作为比较根据旋转角度获得的旋转角度信息信号的相位而获得的相位比较信号来控制滚筒的旋转具有控制信号的相位的滚筒和比较控制装置，用于通过使用通过进行频率去乘法获得的频率去乘数信号来执行相位比较或频率比较来将控制信号输出到旋转控制装置具有高于控制信号的频率的频率的参考信号。因此，当控制信号的相位或频率类似于外部的突然干扰而发生的控制信号的根本变化可以优选地在比较控制装置中被吸收。因此，旋转控制装置可以始终且稳定地跟随在控制信号中发生的突然变化。

摘要： Data is received which is transmitted through a serial bus in a predetermined transmission band. The serial bus is preferably in conformity with the IEEE 1394 standards. One of recording modes for different recording rates is selected in accordance with the transmission band of the received data. The data is recorded in the selected recording mode. Data is reproduced which has been recorded in a recording mode for a predetermined recording rate. A transmission band is allocated, based on the recording mode, for transmitting the data through a serial bus.

摘要： A packet recording/reproducing system is provided which records or reproduces packets on or from tracks formed in time sequence on a magnetic tape. In a recording operation, the packet recording/reproducing system adds to input packets time stamps (3) whose values are synchronous with packet arrival time control clocks produced by the system. The timing with which the packets are recorded on the magnetic tape is controlled by the arrival time control clocks so that a given number of the packets inputted at high data rate are recorded within a one-track area, a two-track area, or a one-track over area defined across at least two of the tracks, thereby minimizing the loss of capacity of the magnetic tape.

摘要： A drum servo system provided with a rotation control device for controlling a rotation of a drum on the basis of a phase comparison signal obtained as a result of comparing the phase of an angle-of-rotation information signal obtained according to an angle of rotation of the drum with the phase of a control signal and a comparison control device for outputting the control signal to the rotation control device by performing a phase comparison or a frequency comparison by use of a frequency de-multiplication signal obtained by effecting a frequency de-multiplication of a reference signal having a frequency higher than a frequency of the control signal. Thus a radical change in the control signal, which occurs when the phase or frequency of the control signal is changed similarly as an abrupt disturbance from the outside, can preferably be absorbed in the comparison control device. Thereby, the rotation control means can always and stably follow the abrupt change occurring in the control signal.
