Abstract
A magnetic recording/playback apparatus for recording information to a magnetic tape and playing back the information from the magnetic tape, includes first and second recording heads which are provided on a rotary cylinder and alternately record information to the magnetic tape. First and second playback heads are provided on the rotary cylinder at predetermined positions relative to the first and second recording heads, and alternately play back the information from the magnetic tape. A crosstalk canceling switch device cancels crosstalk at outputs of the first and second playback heads when the apparatus is run in a read-after-write mode, the crosstalk canceling switch device being set in a closed position during the read-and-write mode and interconnecting the output of the first playback head and the output of the second playback head.
