发明名称 Disc players for reproducing an information signal from a rotating disc
摘要 A disc player for reproducing an information signal from a rotating disc having record tracks defined by successive turns of a spiral signal path in which the information signal is recorded, which is adapted to perform a small scale track jump operation for rapidly moving the reading position determined by a pick-up device in the direction transverse to the spiral signal path on the disc to a relatively short distance repeatedly in the fast forwarding or fast reversing mode and is so arranged that the number of times of the small scale track jump operation performed repeatedly for a certain period in the fast reversing mode is larger than the number of times of the small scale track jump operation performed repeatedly for the same certain period in the fast forwarding mode, whereby the substantial moving distance measured along the spiral signal path in respect of the reading position by the pick-up device moved for the certain period in the fast forwarding mode coincides with or closes to the substantial moving distance measured in the same manner in the fast reversing mode.
