特徴とする信号記録再生装置。[Claims for Utility Model Registration] A signal recording and reproducing device for recording and reproducing signals on a disc-shaped signal recording medium having a plurality of signal recording surfaces in which a tracking servo signal is embedded at a predetermined pitch in at least one signal recording surface. a plurality of signal recording/reproducing elements for transmitting and receiving signals to each of the signal recording surfaces; a pulse generator for outputting a servo gate pulse having the same output cycle as the tracking servo signal; and a switching circuit that supplies the tracking servo signal reproduced from the one signal recording surface to the servo circuit during the gate period, and the servo circuit is configured to control the tracking servo signal regardless of which signal recording surface is being recorded or reproduced. A signal recording/reproducing device characterized in that a tracking servo signal is always reproduced from the one signal recording surface during a gate period of a gate pulse.
