Abstract
PURPOSE:To reduce data error due to step out by detecting a specific period when an error data counted value is minimum and settling the timing in accordance with the detection result. CONSTITUTION:The output signal of a second timing switching means 3 is decoded by a second decoding means 4, and its information pulse is given to an integral comparing circuit 6. This circuit 6 successively counts information pulses at the time of the change of designation of the phase or the like by a timing point changing means 5 and detects a minimum state of the counted value and outputs it to a first timing switching means 1. The first timing switching means 1 demodulates the phase in the least error state and divides data into blocks and outputs data to a first decoding means 2, and decoding like error correction is performed by the first decoding means 2. Since this decoding is performed in the least error state, obtained decoded data has the least error.
