A target generating unit outputs a target value signal of a control target, and a position encoding processing unit outputs a position detection signal of the control target. A PID compensator calculates a control amount for causing the control target to follow a target position based on a difference signal between the target value signal and the position detection signal, and outputs it to an adding unit. A disturbance estimation observer outputs the result of estimation of disturbance to the adding unit. The adding unit adds the control amount output of the PID compensator to the output of the disturbance estimation observer to calculate a total control amount. A storage unit stores a control amount during position control to a fixing position as an attitude difference correction amount, and the disturbance estimation observer performs disturbance estimation using a control amount obtained by subtracting a value stored in the storage unit during position control to a moving position from the total control amount.

Signal processing apparatus

An apparatus for reproducing video data recorded on a tape-shaped recording medium in one of a first recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a first speed and a second recording mode in which the video data is recorded while the tape-shaped recording medium is transported at a second speed different from the first speed, is arranged to reproduce the video data, in the case of a slow reproduction mode, while transporting the tape-shaped recording medium at a predetermined speed irrespective of the recording mode of the video data.

Reproducing apparatus

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.
