Abstract

PURPOSE: To secure an equal speed between recording and reproducing by recording the PCM signals and others with the speed different with every circular region of the different disks and then controlling in steps the revolution speed of the disk based on the reproduction signals.
CONSTITUTION: The information of PCM signals and the like recorded at circular regions 31, 32 and so on of disk 1 in the different revolution speeds is reproduced through head 5. As this reproduced information features different bit frequencies every circular region, resonance circuits 61, 62 and so on produce the resonance output corresponding to the circular regions to read out the matrix-type memory contents of ROM7 in the form of the decision signals of the circular regions. And the division output of program counter 9 is controlled according to the circular regions for motor control circuit 8. Thus the motor of circuit 8 is controlled in steps in accordance with the circular regions to secure the equal speed for both recording and reproducing with every region. As a result, the recording density can be increased if the recording speed is decided higher in accordance with the regions.
