PURPOSE:To make data transfer faster by starting data reading and storing processing upon outputting of an interruption request signal, and continuing to output the above-mentioned interruption request signal. CONSTITUTION:When an interruption request signal is accepted on magnetic disc control device side and a transfer permission signal beings to be received, a buffer controller 10 ends outputting the interruption request signal. If transfer object data is left, storage processing with respect to this data is continued and in parallel with this, data transfer processing is carried out. To accomplish this transfer processing, and read data stored in a track buffer 9 is read out and set into a fetch register 19, and the data is arranged according to order of the data read with a read/write head 11 and is transmitted to the control device side via a driver 24. |
