发明名称 Reproducing apparatus having tracking control in accordance with track number information
摘要 There is provided a reproducing apparatus arranged to reproduce an information signal from a recording medium on which a number of recording tracks are formed in parallel with each other and the information signal is recorded on the recording tracks together with track number information indicative of numbers of the respective tracks, a pilot signal component being multiplexed onto the information signal periodically at intervals of a predetermined number of tracks. When the information signal is to be reproduced from the recording medium, the reproducing apparatus executes tracking control of the reproducing head with respect to a target track, by using the pilot signal component contained in a signal reproduced by a reproducing head. The reproducing apparatus determines the target track according to the track number information separated from the signal reproduced by the reproducing head. According to the above-described arrangement, it is possible to execute correct tracking control quickly after the start of reproduction. In addition, since the track number information recorded on the recording medium in a multiplexed manner is effectively utilized, it is not necessary to provide a special circuit for determining the target track.
