Abstract
A magnetic head is manufactured by grinding a head chip (2) with a gap depth (GD 1) to remove its margin (6) until the gap depth becomes a final gap depth (GD 2). The gap depth (GD 1) is 25 microns or thinner. The method increases yield and productivity in the manufacture of a high performance magnetic head with a decreased gap depth (GD 2), which satisfies the standards of both the gap depth (GD 2) and the distance between the head gap and the outermost point of the chip front.
Claims9
A method for manufacturing a magnetic head, the method comprising grinding a front of a head chip so as to form a front shape of the head chip, wherein a dimension of a gap depth of the head chip before grinding is 25 μm or less.
