Title:
REPRODUCTION DEVICE
Document Type and Number:
Japanese Patent JP3047590
Kind Code:
B2
Abstract:
PURPOSE: To make the phase of reproduction processing proper with simple constitution by detecting a specific address from reproduced data and controlling the reproduction processing phase according to the detected timing.
CONSTITUTION: The processing phase of a reproduction processing circuit 53 is processed with timing pulses which are outputted from a timing generating circuit 11 and supplied to a terminal 12 and the output state of the circuit 11 is controlled with speed setting data supplied to the circuit 11. Further, a subtracter 13 calculates the difference between time data on the timing pulses and reference pulse time data to obtain difference time data. The difference time data is supplied to a subtracter 15, which finds the difference ε of the target phase data outputted by a target phase data generating circuit 16. Further, the phase error ε supplied from the subtracter 15 is subtracted from the difference time data and the value is outputted from a subtracter 25. The specific address is detected from the reproduced data and the reproduction processing phase is controlled at the timing to perform proper control with the simple constitution.
