摘要： PROBLEM TO BE SOLVED: To provide such a magnetic head that it can be used from low relative velocity, and also can achieve a high recording density and a high transfer rate, even when it is used to a flexible magnetic disk. SOLUTION: A head sensitivity S of the magnetic head is defined to become a predetermined value or more from the track width W of a magnetic disk, the amount Mr of residual magnetization and effective medium thickness δ, the relative speed v between the magnetic disk and the magnetic head, an inductance L of the magnetic head, and the isolated time average amplitude ISTAA. When this is applied to the continuous contact type head/medium interface and is combined with a flexible magnetic disk, a recording density and a data transfer rate are enhanced more greatly than before.
