Digital audio signal playback apparatus with scratch effect control device |
摘要 |
In a scratch effect control device for a digital audio signal playback apparatus, a control unit controls output of digital audio data recorded in a data recording medium and read by a data reading device in accordance with a first control signal representative of angular velocity and rotational direction of a first encoder disc and obtained from a first pick-up device, and a second control signal representative of angular velocity and rotational direction of a second encoder disc and obtained from a second pick-up device. The first encoder disc is mounted co-rotatably on an outer sleeve sleeved rotatably on an inner spindle and coupled co-axially to a lower platter member that is driven by a driving unit to rotate about an axis. The second encoder disc is mounted co-rotatably on the inner spindle which is coupled co-axially to an upper platter member that is superposed on the lower platter member.
