Abstract

PURPOSE:To reproduce desired data rapidly and accurately by moving a pickup mechanically to a forecasted position on a disk at a high speed, and then starting search. CONSTITUTION:A motor 50 for disk drive is controlled by a control circuit 51, and an optical system 5 is moved on linear tracking basis by a pickup motor 55 controlled by a control circuit 56. Further, an operation key input is supplied to a music-selecting controller 58 composed of a microprocessor to control the control circuits 51 and 56, and a reproduction signal for detecting an address on a disk 12 is supplied from a decoder 300 to a controller 58. Then, a pickup is moved by the 1st command at a high speed to the circumference where a desired piece of music is expected to reside, and the 2nd command for movement at pitch which is obtained by dividing an expected time for one piece of music by some small number is supplied. Consequently, a desired piece of music is selected rapidly and handling is facilitated.
