摘要： PROBLEM TO BE SOLVED: To provide a polishing tool, a polishing device and a polishing method for uniform polishing work with a polishing pad even if the polishing pad has a poor plane. SOLUTION: When the polishing device containing a polishing tool having a polishing pad 3 held on one face of a thin material 1 extending in the form of one plane is used to polish a machined face of a work 4 held on a work holder 5, the polishing method is adopted in which (A) a guide link 7 is mounted on the work holder 5 so that its polishing plane is flat with the machined face of the work, (B) the machined face of the work 4 and the polishing plane of the guide link 7 are pushed against the polishing pad 3 with a fluid having the same pressure, and (C) the polishing pad 3 is moved relative to the work 4. If required, a portion 3a of the polishing pad 3 is pushed against the machined face of the work 4 using the pressure of the fluid in polishing work.

摘要： PROBLEM TO BE SOLVED: To remarkably reduce frictional heat generated between a working surface of a polishing pad and a retainer ring by rotating the retainer ring following the polishing pad by receiving rotational force of the polishing pad when the polishing pad is moved on the retainer ring. SOLUTION: A retainer ring 34 is supported on a sucking table 24 and the supporting base part 27 in a freely ratable state by interposing a bell bearing 37. As a result, when a polishing pad 30 is moved on the retainer ring 34, the retainer ring 34 is rotated following the polishing pad 30 by receiving rotational force of the polishing pad 30. Therefore, the existence of the retainer ring 34 does not become remarkably large resistance for rotation of the polishing pad 30 and frictional heat generated between a working surface 30a of the polishing pad 30 and the retainer ring 34 is remarkably reduced. Therefore, excellent flat performance can be secured for a comparatively long period.

摘要： PROBLEM TO BE SOLVED: To provide a grinding height position setting method for grinding device capable of performing correct setting by preventing damage to a grinding head when a sensor height original point to determine a grinding height position is set. SOLUTION: Before starting a grinding operation, a contact rod 10 provided with a grinding tape 8 is brought in contact with a correction table 15 so as to set a height of sensors 3a and 3b to detect the surface of the correction table 15 as a height original point. Also, because the correction table 15 is formed so that a table 16 comprising a rigid body is supported by an elastic supporting body 14, it is sunk according to a pressing force at the time of contact with the contact rod 10. As a result, the contact rod 10 is not damaged. In addition, because it is brought in contact by point contact with the top end of the contact rod 10, accurate height original point can be set.

摘要： PURPOSE:To provide the process for production of the thin-film magnetic head which eliminates an improves errors of thin film components, film thicknesses, resistor disconnection, etc., and can uniformly work plural heads to the gap depth of high accuracy in the process for production of the head to be used for a magnetic recording and reproducing device of a digital system. CONSTITUTION:Resistors R1 to R3 are provided at both ends of the multitrack thin-film magnetic head bar and the value of R3 is measured prior to grinding and is compared with a theoretical value. The resistance values of R1, R2 are then corrected. Control is executed by using the R1 at the time of grinding. The uniform grinding of the gap with the high accuracy is thus executed without being affected at the time of ending the working.
