Abstract

The present invention is directed to a recording/reproducing apparatus having a Read After Write function which simultaneously performs recording operation and reproduction operation, and is such that, in a reproducing system () of a tape streamer () which performs Read After Write operation for signals through a magnetic tape (), the apparatus serves to distribute reproduction signals obtained from the magnetic tape by a first data distribution switch () to store signals thus distributed into frame memories (A), (B) of 2 channels, and to distribute a recording signal from a recording system () by a second data distribution switch () as cause signals of crosstalk signals included in reproduction signals to store signals thus distributed into frame memories to generate pseudo crosstalk signals of respective channels by crosstalk cancellers (A), (B) on the basis of reproduction signals and cause signals of respective channels which are read out from the frame memories to cancel, every channel, crosstalk signals included in reproduction signals of respective channels.
