Abstract
PURPOSE: To reduce errors due to the skew by retrieving data in the direction of the skew even when the large skew exists in one data group.
CONSTITUTION: Data are set in data buffer 1, wind signal (g) of the 1st gate circuit 2 operates detecting circuit 3 for every track at its rise, and the 1st arrival dara enters detecting circuit 3. The contents of detecting circuit 3 are transferred to shift registers 4 and 5 after a certain time of the fall of wind signal (g), and those of the data buffer also enter registers 6 and 7. A CP signal is inputted to shift registers 4 and 5 to make shifts to right or left. Then, N CP terminals of shift registers 6 and 7 correspond to outputs, one to one, and the contents of data buffer 1 are transferred according to tracks. On the completion of the shifts, a parity ckeck is made and the contents of registers 6 and 7 are sent to skew buffer 11.
