摘要： In an apparatus for recording and reproducing a burst-like digital information signal, a method capable of predicting the time of occurrence of a header indicating the head of the first data of a digital information signal during its reproduction from a recording medium. The digital signal includes a plurality of data blocks each including a header indicative of the head of the block, and each header includes the address of the block. During recording of the digital signal on the recording medium, a plurality of headers which are substantially the same as the headers of the data blocks and including addresses having given relations with the addresses of the data blocks are inserted in a clock regenerating signal recorded before the digital signal for regenerating the clocks for the signal. The headers are inserted at a period equal to the length of each data block so as to be synchronized with the headers of the data blocks.

Index codes for a video signal, which enable a search reproduction and so on, are recorded on a video tape in a constant transmission rate irrespective of the transmission rate of a PCM audio signal to be recorded. Further, an amble pattern at the same frequency as the transmission rate of the PCM audio signal is recorded immediately behind the PCM signal recording area. A reproducing apparatus may be provided only with an index detecting circuit corresponding to the constant transmission rate.

摘要： An optical disk reproducing apparatus for reproducing at a high access-speed an optical disk on which data has been recorded at a constant linear velocity (CLV) includes a control circuit for controlling reading of the disk recorded at a CLV to be rotated at a constant angular velocity (CAV), and a processor for changing the frequency of a reference clock to determine the processing timing of the reproduced digital signal in accordance with a transmission speed of the digital information signal picked up from the disk. A motor for driving the disk can be rotated at a constant revolution rate upon access to the disk, and thus it is possible to remove one of the factors for determining the access time in the conventional CLV type reproduction system, or the time for controlling the motor to rotate for a constant linear velocity in accordance with the position of the optical pickup.
