Title: Data reproducing device
Inventor: SHIMIZU TADASHI
IPC: G11B20/14
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a data reproducing device which can assure the reliability of data reproduction and is flexibly used to reproduce data of various disks although the constitution is simple. SOLUTION: The binarized signal outputted from a binarizing circuit 4 is delayed by a signal delay adjusting circuit 7 and supplied to a data demodulating circuit 8. Consequently, even if phase control over a PLL circuit 6 becomes unstable since bits recorded on a disk 1 shift from their original positions and the binarized signal obtained by reproducing the bits has a bit shift and the bit shift tends to generate over the whole, the phase control can indirectly be secured by delaying the binarized signal. The signal delay adjusting circuit 7 individually delays the positions of leading and trailing edges of the binarized signal and the delay quantities are determined through the error correction of the data.
