Title: Magnetic transducer and method for detecting floating hight
Inventor: WADA KOSEI
IPC: G11B21/21
Filed: 1990-11-30
Abstract: PURPOSE:To attain high density in recording and reproduction by providing a sub-slider part supported by a main slider, having a detecting part which indicates the sub-slider part comes into contact with protrusions on the surface of a recording medium and thereby selecting the floating hight that allows to record and reproduce without being in contact with the protrusions. CONSTITUTION:This device is provided with the main slider 3 that floats by a wind pressure generated by the revolution of a recording medium, the sub- slider part 3a that is supported by the main slider 3, a variable means 8 that varies the hight of the sub-slider part 3a, and the detecting part 9 that indicates the sub-slider part 3a comes into contact with the protrusions produced on the face of the recording medium. Consequently, recording and reproduction are performed by pressing down the sub-slider face 4 down to the hight that is not in contact with the protrusions produced scatteredly on the face of the medium. Thus, the high density of recording and reproduction onto the disk is attained.
