摘要 |
An apparatus for reproducing information signals recorded in spiral or coaxial tracks of a record disc includes a pick-up device operative, upon scanning of a track of the disc while the latter is rotated, to reproduce the information signals recorded in the scanned track; a driver for rotating the record disc relative to the pick-up device; a tracking device for controlling the tracing of the tracks by the pick-up device; a transporting device for bodily moving the pick-up device in a radial direction in respect to the axis of rotation of the record disc and thereby normally determining the tracks to be scanned by the pick-up device; and a controller selectively operative for causing the pick-up device to intermittently trace nonadjacent groups of tracks so as to intermittently reproduce the information signal recorded in the nonadjacent groups of tracks, respectively.
