HEATING TEST DEVICE OF THIN FILM MAGNETIC HEAD AND HEATING TEST METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To heat only a thin film magnetic head till a set temperature with high precision without bringing a heating means into contact with the thin film magnetic head and in a short time.;SOLUTION: A heating test device of the thin film magnetic head is provided with an arm section 3 for fixing the thin film magnetic head 1 being a testing object, an input device 22 for setting a test temperature Ta of the thin film magnetic head 1, a laser source 4 for emitting laser beams, a focusing member 4a for focusing laser beams from the laser source 4 and emitting the beams to the thin film magnetic head 1, a resistance measuring apparatus 7 for measuring resistance value of the thin film magnetic head 1 and a comparing judging section 20 which compares resistance values of the thin film magnetic head 1 before and after irradiation with the laser beams and has a judging function for performing normal/defective condition decision.;COPYRIGHT: (C)2002,JPO
