ABSTRACT:
In a CD type disk player, main data in a digital signal, which is read from a CD type disk traced by a pickup, is decoded in a decoding means in accordance with a bit clock regenerated in a clock regenerator. Both the writing and reading of the data into and from a memory can be synchronized with the bit clock. Also, a selector can switch over the operation clock of the decoding means, thereby selecting the more important factor, either time base precision or decoding ability, in correspondence with the kind of disk. While avoiding the enlargement in size and power consumption of the disk motor, the read out of the information from the disk can be conducted at a higher speed.
