MAGNETIC HEAD FOR RECORDING/REPRODUCTION, MAGNETIC RECORDING MEDIUM, AND RECORDING/REPRODUCTION APPARATUS |
摘要 |
A magnetic recording medium constructed as a discrete track-type medium. The magnetic recording medium is constructed so that a track width of data recording tracks is equal to or smaller than a width produced by subtracting twice an off-track width of a magnetic head with respect to the data recording tracks during a recording of the recording data from a magnetic effective recording head width of the magnetic head. The track width is equal to or smaller than a width produced by subtracting twice an off-track width of the magnetic head 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. A combined width of the track width and twice a width of the non-magnetic parts is 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.
