Abstract
In the case that an analog signal is recorded or reproduced by using a sensor and recording medium relatively moving against the sensor, a sampling signal is generated which is adapted to have a frequency thereof deviated dependently upon an amount of wow and flutter caused by fluctuations in the speed of the relative motion therebetween. A reproduced signal is sampled by means of the sampling signal and, a sampled signal is stored in a memory. After this, a stored contents in the memory are read out by using a reading signal with a predetermined frequency, thereby to remove from the reproduced signal varying frequency components caused by the wow and flutter.
