    摘要: A magnetic recording/reproducing apparatus in which the reproduced audio data is processed and is recorded in every N cycles during which the reproducing magnetic heads scan a pair of recording tracks. The recording magnetic head is positioned behind the reproducing magnetic head for 8.5+4N track pitch, so that a write-after-read processing is provided. Using the recording head positioned behind the reproducing head, the reproduced audio data is stored in a memory for time base compression or expansion, and in a multichannel mode the reproduced audio data is read out and recorded performing write-after-read processing even if the number of channels is changed. The 2.sup.n channel audio data is recorded using interleave processing in every N cycles of the heads forming a pair of recording tracks so that even if the cycle in which a pair of recording tracks is not an integral multiple of the sampling cycle, the plural channels of audio data can be recorded and/or reproduced.

    摘要: A digital audio tape recorder signal processor whose signal processing period is Td performs signal processing for recording 2-channel PCM signals having a sampling frequency of Fs. A circuit is provided for compressing the time-base of 4-channel PCM signals by one-half to form 2-channel time-base-compressed PCM signals in which the first and second channels are time-divided and multiplexed and the third and fourth channels are time-divided and multiplexed, so that when the time-base-compressed PCM signal is supplied to the signal processor, the signal processor is operated with a sampling frequency of 2Fs and the signal processing period is changed to 1/2 Td.

    摘要: A data transmitting system uniformly processes and transmits data by taking a plurality of samples of an analog signal and generating bits forming digital words respectively corresponding to the samples, the number of bits representing each sample being switchable between a plurality of values M and N. First input data is supplied in first words of which each consists of M bits and second input data is supplied occurring in second words of which each consists of N bits. An a-th first word in each M-bit first input data is defined as W.sub.a. The first input data is divided into k kinds of sets of (W.sub.nk+1), (W.sub.nk+2), . . . , (W.sub.nk+k), where n is an arbitrary integer. A b-th word in each N-bit second input data is defined as W.sub.b. The second input data is divided into k kinds of sets of (W'.sub.nk+1), (W'.sub.nk+2), . . . , (W'.sub.nk+k), the number of bits of the first words of the set of (W.sub.nk+m) (m being an integer from 1 to k) being equal to the number of bits of the second words in the set of (W'.sub.nk+m). The data separately processed and transmitted in each of the sets.

    摘要: A reproducing apparatus for reproducing blocks from a recording medium on which a plurality of signal blocks are recorded on plural recording tracks, uses a rotary head which is rotated at a speed equal to at least twice the normal speed. Error detection of a reproduced signal is performed for each signal block, and a detection signal and a reproduced signal of the corresponding signal block are written into a memory. If the detection signal indicates that no error is detected, the reproduced signal from the corresponding signal block is prevented from being written again into the memory. A reproduced track address signal and a reference track address signal are compared, and in accordance with the comparison result, translation of the recording medium is controlled.

    摘要: A rotary head type digital tape recorder in which a PCM signal and sub data for control and the like concerned with the PCM signal are recorded and/or reproduced by rotary heads. The invention relates to a method and apparatus for transmitting and/or receiving a digital signal in such a type of digital tape recorder by using a data format such that when the serial data is input and output each of a predetermined number of words of the reproduced PCM signal and each symbol of the reproduced sub data are transmitted as a pair synchronously with the rotation of the rotary heads. Thus, a large amount of sub data can be input and output together with the PCM signal.
