Zusammenfassung:PROBLEM TO BE SOLVED: To control the size of a depth with high precision by polishing the medium slide surfaces of a plurality of MR heads at one time. SOLUTION: Polishing is applied on medium slide surfaces 102a of a plurality of magnetic head assembly 100 one time by a polishing device 1 having a plurality of sub-holders 10 to hold a magnetic head assembly 100. In this case, the resistance value of the magnetic head assembly 100 during polishing is always measured. Only the sub-holder 10 holding the magnetic head assembly 100 adjusted to a given resistance value is moved in a direction separating away from a polishing tape 11 and polishing of the magnetic head assembly 100 is completed.
