Abstract

PURPOSE:To enable the alignment of a transducer with very high accuracy, by sliding and moving the transducer along radial direction of a disc recording medium through a conversion means converting a rotating torque from a rotating drive means into a linear motion. CONSTITUTION:A rotating drive force from a step motor 25 is slided along the radial direction of a magnetic disc 3 for a magnetic head 20 with a feed screw 28 and a stylus member 38. The 1st position detecting means 55 detecting radial position of the magnetic head 20 and the 2nd position detecting means 56 detecting the rotating position of the rotating drive means are respectively provided. The alignment of the magnetic head 20 can be made with the position detecting means 55, 56. Through the combination between the means 55 and the means 56, even if each means has a low accuracy for detection, the detection with very accurate result can be made.
