Verfahren zum Positionieren eines Schrittmotors für ein Wiedergabe- und/oder Aufzeichnungs- und/oder Ausgabegerät für Platten und ein solches Gerät hierzu

摘要

A playback, recording and/or extracting machine for disks designed as information carriers has opposite disk magazines (4) that receive disk-holders (7) for at least one disk (1) in horizontally superimposed disk-receiving compartments (6) and a computer-controlled transport device (10) arranged between the disk magazines (4) and provided with two horizontally movable drawing-out means (9) for the disk-holders (7). In order to monitor the driving motor (25; 36) of the transport device (10) and drawing-out means (9), the driving motor (25; 36) is connected to an incremental signal generator (74) that incrementally detects the position of the driving motor (25; 36) and thus allows the transport device (10) and drawing-out means (9) to be automatically and precisely positioned.
