Abstract
Signal processing method and apparatus are provided for use in a digital signal reproduction apparatus which reproduces data divided into plural channels and recorded in plural tracks in parallel. Time division operation is applied to digital signals of plural channels read out from plural tracks for every associated reproduction head and at intervals of predetermined unit time interval. In each unit time interval, digital signals of n consecutive units (where n is an integer not less than 2) supplied from associated reproduction heads are multiplexed with a multiplexing factor of n. The above described multiplexed signals of n units supplied from an identical reproduction head are stored into identical addresses of m (where m is an integer not less than 2) memories, respectively. Digital signals supplied from every reproduction head are successively stored into a different address in each memory. Signals stored in identical addresses of the above described respective memories are read out simultaneously and then signals of respective addresses are read out successively.
