Improved magnetic head having smoothed chamfered surface for reducing
magnetic scattering
摘要:
At least the first chamfered portion 22 for forming the apex portion 8 has a surface roughness (R.sub.p-p) of 0.6 .mu.m or under. This first chamfered portion 22 is formed through grinding with a #2500 or #1500 grinding stone.
