Abstract

PURPOSE:To make relative speeds of a head and a disc fixed with a simple constitution and a high precision by controlling the rotation speed of the disc and the moving speed of the recording head by an electric circuit. CONSTITUTION:Turntable 2 is rotated and driven by synchronous motor 3, and moving stand 5 where recording head 4 is fixed and mounted is screwed with screw bar 7 rotated and driven by synchronous motor 6. Count 9 of the output of oscillator 8 is started by the start signal of terminal 10 when head 4 is placed in a position of outside circumference of oscillator 8 is started by the start signal of terminal 10 when head oscillator 12 after A/D conversion. The output of oscillator 12 is subjected to frequency division by 13 and 15 and is applied to motors 3 and 6. Consequently, the number of disc rotations is changed successively by recording positions of head 4 in the diameter direction of disc 1, and a spiral recording locus is described at a fixed pitch while keeping relative speeds of head 4 and disc 1 fixed.
