A digital signal processing circuit having a memory of a predetermined capacity is provided, and the number of digital data to be recorded in one data frame is varied in accordance with a difference between the number of input data of the digital audio signal to the digital signal processing circuit and the number of output data supplied to the record medium for recording. In the recording mode, the PCM audio signal is sectioned into blocks, a data block address signal is added to each block to indicate a relative order of a block to the other blocks and is completely added in one track, certain number of blocks are combined to form a block set for processing signals, and an identification signal completing in the block and an interleave block address signal for indicating a relative order to other blocks are added to each block.

摘要： A method of producing a tracking control signal in a rotary head type magnetic recording and reproducing apparatus and a rotary head type magnetic recording and reproducing apparatus capable of a proper tracking by the use of the tracking control signal. First and second tracking signals are recorded on local portions of each odd-numbered track and the first tracking signal and a third tracking signal are recorded on local portions of each even-numbered track in such a manner that the second tracking signals on two odd-numbered track adjacent to any one even-numbered track are not overlapped with each other and the third tracking signals on two even-numbered tracks adjacent to any one odd-numbered track are not overlapped with each other when viewed in a direction perpendicular to the longitudinal direction of the tracks; upon scanning of a track crosstalk signals are detected from two adjacent track simultaneously with reproduction of the first and second or third tracking signals; and the detected crosstalk signals are compared by the use of timing of the reproduction of the first tracking signal for each track thereby producing a tracking control signal. The second tracking signal may have a frequency equal to that of the third tracking frequency.

摘要： In a digital information recording and reproducing apparatus of a rotary magnetic head type for selecting and recording a plurality of digital information signals having different transmission rates and for selectively reproducing the recorded signal, a high-rate digital information signal and a low-rate digital information signal are inputted for selection of either one thereof to be converted by a recording-system encoder into two channels of recording signals. When recording the high-rate signal, the rotary drum is turned at a rotation speed and the magnetic tape is fed at a feed speed (V1) to conduct 4-track azimuth recording of the signals for each rotation of the rotary drum by the first to fourth magnetic heads. To record the low-rate signal, the rotary drum is turned at a rotation speed substantially equal to the first rotation speed and the magnetic tape is fed at a feed speed almost equal to (V1/N) so as to achieve 4-track azimuth recording of record signals compressed on a time axis to 1/N of the original signals for every N rotations of the rotary drum by the magnetic heads. A reproducing system receives two channels of signals reproduced by the first to fourth magnetic heads and conducts for the signals such processes reverse to those of the encoding process of the recording system.

摘要： A digital information recording-reproducing apparatus is disclosed, in which a signal temporally compressed to 1/n and transmitted is encoded for recording by a recording encoder. The rotation speed of a rotary drum is set at R.sub.1, and the running speed of a magnetic tape at V.sub.1. The signal encoded is recorded on the magnetic tape by magnetic heads. At the time of reproduction, the rotary drum is driven at a speed m/n times faster than for recording, and the magnetic tape is run at a speed 1/n times faster than for recording. The signal reproduced by the magnetic heads is decoded and restored into the original digital information signal by a reproducing decoder. As a result, there is provided a recording-reproducing apparatus having the function of time-base expansion with a reduced recording time applied to a system for transmitting and recording the software information of video or the like through radio wave or cable.
