Abstract:
1. A magnetic head for recording/reproduction constructed so as to be capable of recording recording data onto and of reproducing recording data from a discrete track-type magnetic recording medium on which a plurality of concentric data recording tracks, which are magnetically separated by non-magnetic parts, are formed, wherein the magnetic head for recording/reproduction is constructed so that a magnetic effective recording head width of the magnetic head for recording/reproduction is equal to or larger than a combined width of a track width of the data recording tracks and double an off-track width of the magnetic head for recording/reproduction with respect to the data recording tracks during a recording of the recording data and is equal to or smaller than a width produced by subtracting double the off-track width during the recording from a combined width of the track width and double a width of the non-magnetic parts, and a magnetic effective reproduction head width of the magnetic head for recording/reproduction is equal to or larger than a combined width of the track width and double an off-track width of the magnetic head for recording/reproduction with respect to the data recording tracks during a reproduction of the recording data and is equal to or smaller than a width produced by subtracting double the off-track width during the reproduction from a combined width of the track width and double the width of the non-magnetic parts.
