Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To control working correctly and constantly by eliminating an abnormal detected value extremely deviated from detected values by a plurality of sensors using a smoothing method and controlling working. SOLUTION: In respective sets, MR heights is determined by detecting and calculating resistant values R1 and R2 of a first and a second resistance lapping guide(RLG) sensors 54 and 55. The MR height is calculated by the equation HMR=(C+S.W1 )/R1 -RL), or HMR=(C+S.W1 )/(R2 -RL); RL: parameter inherent to a bar, R1 and R2 : detected resistant data). An RLG sensor showing extremely deviated abnormal value judged wholly is invalidated by using a smoothing method. That is, the detected values from such a RLG sensor are eliminated. A 4th regression curve is calculated by the MR height calculated from the resistance of remaining RLG sensors, and the MR height is ground while driving a linear DC motor in an RLG working machine to suppress the bending of a bar so that the regression curve becomes a straight line.

Title: Magnetic recording medium
Inventor: KISHIMOTO MIKIO
IPC: G11B5/738
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To enable the writing of a servo signal with a low recording current and to protect the servo signal from being erased and rewritten by forming a primary-coating layer including MnBi magnetic powder for recording a signal for servo control on a non-magnetic supporting body. SOLUTION: The coercive force of MnBi magnetic powder is high to be about 12000Oe at 300K and, however, it is lowered to be not larger than 1500Oe at 100K when a temp. is lowered. Consequently, the powder can be degaussed (an initialization) by cooling it to a low temp. which utilizing this property and after it is degaussed, it can be easily magnetized at room temp. Moreover, however a magnetic disk using this MnBi magnetic powder can be easily magnetized with the low magnetic field of the order of 2000Oe at room temp, after the initialization, when the disk is magnetized once, the disk becomes so as to show the high coercive force of the order of 12000Oe and it becomes very difficult to perform subsequent data erasing and rewriting. Moreover, the output of the magnetic disk using the MnBi magnetic powder is hardly lowered even by the erasing current of 7mA.
