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.

摘要： A method of moving a pick-up device of an optical reproducing apparatus to a position corresponding to a desired address of a record disk, the record disk having an information signal and an address signal recorded in an information area thereon, comprising the steps of producing a desired address signal corresponding to the desired address; partitioning the information area into radially partitioned information sections; moving the pick-up device to a position between two adjacent radially partitioned information sections at a speed faster than normal reproducing speed; reproducing the address signal at the last position of the pick-up device; comparing the reproduced address signal at the last position with the desired address signal; further moving the pick-up device in a direction and an amount determined by the comparing step to a position between two adjacent radially partitioned information sections and within one of the radially partitioned information sections between which the pick-up device was last positioned at a speed faster than the normal reproducing speed; and repeating the steps of reproducing, comparing and further moving until the pick-up device is moved to the position corresponding to the desired address. Apparatus for performing the above method is also provided.
