PROBLEM TO BE SOLVED: To provide a sampling control circuit suitable for a disk player capable of recording a signal on the disk and also carrying out the reproducing action of the signal recorded on this disk. SOLUTION: This control circuit is constituted of a signal amplifier circuit 9 for a main beam amplifying a signal obtained from a photodetector 6 for the main beam, a signal amplifier circuit 10 for a sub-beam amplifying signals obtained from photodetectors 7, 8 for the sub-beam, a sampling circuit 12 for the main beam outputting a signal outputted from the signal amplifier circuit 9 for the main beam at the specified timing and a sampling circuit 13 for the sub-beam outputting a signal outputted from the signal amplifier circuit 10 for the sub-beam at the specified timing. |
