ABSTRACT:
A data recording and reproducing apparatus capable of coping with various applications has been difficult to be realized. In the data recording and reproducing apparatus, a plurality of first input/output sections, a data recording and reproducing section for recording data transmitted via a data bus from the first input/output sections on the recording medium while reproducing data recorded on the recording medium to transmit the data to the corresponding first input/output section via the data bus, and a control means for giving a useful right for the data bus to each of the input/output sections by a predetermined time in order are connected to one data bus, with the result that each of the input/output sections occupies the data bus only when the useful right is given from the control section, to transmit the data to the data recording and reproducing section via the data bus within the predetermined time or to take in the data which is transmitted via the data bus from the data recording and reproducing section.
