Abstract

A REPRODUCING APPARATUS (RAP) FOR DISK-SHAPED RECORDING MEDIUM ROTATIONALLY DRIVES THE DISK-SHAPED RECORDING MEDIUM (1) AT A PARTICULAR SPEED (N) TO READ INFORMATION FROM A RECORDING TRACK DISPOSED CIRCUMFERENTIALLY TO THE CENTER OF THE RECORDING SURFACE WITH INFORMATION RECORDED AT A CONSTANT LINEAR VELOCITY. A PICKUP MEANS (6) SCANS THE RECORDING TRACK AND GENERATING A FIRST REPRODUCTION SIGNAL. A FIRST ROTATIONAL DRIVE CONTROLL MEANS (21) ROTATES THE DISK-SHAPED RECORDING MEDIUM (1) AT A CONSTANT LINEAR VELOCITY (CLV) BASED ON THE REPRODUCTION SIGNAL, AND A SECOND ROTATIONAL DRIVE CONTROL MEANS (22) ROTATES THE DISK-SHAPED RECORDING MEDIUM (1) AT A CONSTANT ANGULAR VELOCITY (CAV). A ROTATIONAL DRIVE CONTROL MEANS SELECTION MEANS (20, 16) SELECTS THE FIRST ROTATIONAL DRIVE CONTROL MEANS (21) OR THE SECOND ROTATIONAL DRIVE CONTROL MEANS (22) BASED ON THE POSITION OF THE PICKUP MEANS (6) WHEN REPRODUCING THE DISK.
