Title: Head for magnetic disc
Inventor: TANAKA YOSHITO
IPC: G11B11/14
Filed: 1985-08-07
Abstract: PURPOSE:To attain simultaneous measurement of minute gap and a magnetic converting characteristic by clipping a magnetic core measuring the electromagnetic conversion characteristic between a head and a disc by an optical head measuring optically the minute gap to a carriage. CONSTITUTION:The magnetic head 5 is placed on the disc 6 and a monochroic light or white light is made incident from the upper part as an incident light 7. The light incident in an optical chip 1 and an optical slider 2 of the magnetic head 5 is reflected in the lower face of the optical chip 1 and the lower face of the optical slider 2 and becomes a reflected light 7a. Further, the light reflected in the surface 6a of the magnetic disc 6 becomes a reflected light 7b and both the reflected lights 7a, 7b are interferred mutually to cause an interference fringe. In this case, a gap (d) is a dark line at d=mlambda/2 and a bright line at d=(2n+1)lambda/4, where lambda is a wavelength of the incident light 7 and (n) is the order of interference. Thus, the gap (d) is measured at a position of the magnetic head by the measurement of the interference fringe to conduct the gap measurement of the magnetic head and the measurement of the electromagnetic conversion characteristic at the same time.

Title: Initialization method for recording medium
Inventor: TSUCHINAGA HIROYUKI
IPC: G11B7/0055
Filed: 1992-06-30
Abstract: PURPOSE:To eliminate the fluctuation in the level of a reproduced signal of a phase shift optical disk of an overwriting type by suppressing the fluctuation in the width of the uncrystallized regions generated in the course of recording. CONSTITUTION:The reference clock signal formed from the prepit information embedded in the disk is frequency-divided by two to form two patterns 14, 14' for initialization which are synchronized with the reference clock signal and are inverted in phase. The progression of the crystallization of the uncrystallized regions 13' generated in the peripheral parts of the recorded amorphous pits 15, 15' is satd. by alternately overwriting of these patterns plural times, by that, the spread of the width of the crystallized tracks 12 at the time of recording is made invisible. The appearance of the fluctuation in the width of the crystallized tracks is obviated even after the formation of the recording pits and the uncrystallized regions are no longer caught in a laser beam for reproduction and, therefore, the fluctuation in the level of the reproduced signal is eliminated. Consequently, the detection error arising from the fluctuation in the level of the reproduced signal is suppressed.
