DISC PLAYERS FOR REPRODUCING AN INFORMATION SIGNAL FROM A ROTATING DISC ABSTRACT OF THE DISCLOSURE A player for reproducing an information signal from a rotating disc having record tracks having a spiral signal path in which the information signal is recorded. The player is adapted to perform a small scale track jump operation for rapidly moving the reading position in directions transverse to the spiral signal path by relative- ly short distance repeatedly in the fast forwarding or fast reversing mode. The movement is so arranged that the number of times of the small scale track jump operation is performed repeatedly for a 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 period in the fast forwarding mode. By this means, the moving distance along the spiral signal path in respect of the reading position by a pick-up device moved for the period in the fast forwarding mode substantially coincides with moving distance measured in the same manner in the fast reversing mode.
