Title: Magnetic erase head and driving method therefor
IPC: G11B5/265
Filed: 1991-11-29
Abstract: PURPOSE:To obtain excellent erase characteristics. CONSTITUTION:The length of the magnetic tape traveling direction, until generation magnetic field strength of a magnetic erase head becomes from 0 to the maximum, is at least 1/3 of the head gap length, and erase current frequency is made such that the magnetic tape suffers 3 times erase magnetic field inversions within the time in which the magnetic tape passes the length of the magnetic tape traveling direction. Thus, since the magnetic tape is applied plural times magnetic-field inversions and decreasing magnetic field strength, when the tape passes a head magnetic field, the erase properties are enhanced.
