Abstract
A method of manufacturing a hybrid type magnetic head slider using a thin film coil in which a number of cores can be manufactured in the sane condition, and improvement and uniformity in yield and performance can be expected. A conductor pattern forming a plurality of thin film coils (2b) and a magnetic material (magnetic cores 2a) passing in the thin film coils are formed on a nonmagnetic base (1) by means of spattering or the like, and grooves (15) for bonding a plurality of ferrite made head cores (13) are formed on a different nonmagnetic base (14). The ferrite made head cores, which are bonded by glass thin films with a fixed gap, are bonded after polished into the outer dimension fitted to the grooves. A thin film coil stick (4) having the thin film coils formed thereon and a head core base (16) having the head cores bonded thereto are combined and bonded together to form a magnetic head slider bond bar (20), which is then cut and subjected to a polishing, whereby a magnetic head slider is completed reducing manual work.
