Abstract

PURPOSE:To perform stably and surely time base correction and tracking correction by separating the operation mechanism of the vibration system into the time base correction direction and the tracking correction direction and by making magnets and coils driving them independent of one another. CONSTITUTION:Cartridge housing 32 is provided in cartridge feeding mechanism 31 so that housing 32 can be fitted and removed freely. Arm 41 is supported by holder 34 through damper 35, and stylus chip 43 is brought into contact with disc 10 and is pressurized by electrode lead 44 used as a spring also. Permanent magnets 36 and 46 are mounted on the upper end of holder 34 and the back end of arm 41 in directions shown in the figure, coils 51 and 52 are provided in position opposite to magnets 36 and 46. Then, when a time base correcting signal is supplied to coil 51, magnet 36, namely, chip 43 is displaced minutely in the length direction of the track to correct the time base error; and when a tracking correcting signal is supplied to coil 52, the back end of arm 41 is displaced minutely with damper 35 as a fulcrum to correct the tracking error.
