<p>In a disk recording/reproduction apparatus, the operational limit of cach of a mechanical apparatus and signal proccssing scction of the disk drive is taken into consideration. When an area from the innermost rcgion of a disk to a predetermined radius is recorded or reproduced, the disk is rotationally, driven by a Constant Angular Velocity (CAV) mcthod, and whcn an area from the predetermined radius of the disk to the outermost region is recorded or reproduced, the disk is rotationally, drivcn by a Constant Linear Velocity (CLV) method. <IMAGE></p> |
