Date Sep. 12, 1986.In order to reach precisely a predetermined place on an audio disk during a search run with contactless scanning, the scanning speed is determined from the speed of rotation of the disk. This occurs preferably at the beginning of the first recorded piece. The information concerning the speed of rotation of the disk is determined from the radial error signal. The arrangement is adapted for determining scanning speeds that vary among disks, and where each disk has a scanning speed that is unique to the disk and differs from the scanning speed of another disk.
