Abstract
PURPOSE: To increase the data processing efficiency, by switching the clock controlling the error correction code circuit to high speed clock and performing the analysis and correction of error correction code in high speed, when the presence of data error is detected.
CONSTITUTION: The data read in at the read-in head of the magnetic disc 3 is fed to the error correction code ECC circuit 11 of the controller 2 for analysis work of error, and the correction code is generated in case the error possible for the correction of location in error. Further, the data read in is fed to the synchronizing frequency oscillator 10 consisting of VCO forming the clock, and the clock formed at the oscillator 10 is fed to the switching circuit 15 and the clock from the high speed clock oscillator 16 producing high speed clock from the oscillator 10 is fed to the circuit 10. Moreover, if the presence of error is detected, the clock controlling the FCC circuit 11 is switched into high speed clock at the transfer control circuit 14 and the analysis and correction of the error correction code are processed in high speed.
