PURPOSE:To reduce the waiting time of readout circuit, by providing a bus outputting a readout storage information via a shift register circuit of one storage block or more. CONSTITUTION:A data segmented and stored into a plurality of sectors at a magnetic disc device is read out from a rotating recording medium 1, and one is transmitted to the main storage section as the data through a data readout control circuit 2 directly. Another is inputted to a shift register circuit 3 having greater storage capacity than one storage block of split sector. The output data through this shift register circuit 3 and the direct readout data are switched at a gate circuit 4 and transferred to the main storage section. If the sector to be read out passes through the head location, the data of passing sector stored in the shift register 3 can be read out directly. |
