Patent ID: 7457082

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