スクプレイヤーのパルスモーター制御回路。 A pulse motor driven to move the pickup in the radial direction of the disk, excitation pattern storage means for storing the phase to be excited of the pulse motor, counter means for sequentially reading out the contents of the excitation pattern storage means, and the counter. The method is to use a 1-2 phase excitation pattern when playing a disc player, and a 2-phase excitation pattern when fast forwarding a disc player.
A pulse motor control circuit for a disc player, comprising means for reading a phase excitation pattern from the excitation pattern storage means.
