Abstract:
1. A magnetic head test method for testing a magnetic head of a magnetic head assembly by clamping said magnetic head assembly having a mounting base on which a mounting hole having a protruded peripheral edge is provided, on a head clamp table and reading data from a magnetic disk by said magnetic head of said magnetic head assembly, comprising the steps of: providing a clamp mechanism for positioning and clamping said magnetic head assembly on said head clamp table in a predetermined one axis direction through said mounting base of said magnetic head assembly with respect to said magnetic head assembly mounted on said head clamp table by fitting said mounting hole in a positioning pin standing up from said head clamp table; storing a plurality of non-tested said magnetic head assemblies in a tray by fitting said mounting holes of said non-tested magnetic head assemblies in a plurality of boss pins or a plurality of receiving holes of said tray, respectively; transporting one of said non-tested magnetic head assemblies from said try to a mounting table having a pin or a hole by positioning a suction portion of a handling robot in a position of one of said boss pins or one of said receiving holes and sucking up said one of said non-tested head assemblies from said tray, mounting said one of said non-tested magnetic head assemblies on said mounting table by positioning said suction portion using the position of said pin or said hole of said mounting table as a reference and fitting said mounting hole thereof in said pin or said hole of said mounting table and releasing a sucking operation of said suction portion; positioning said one of said non-tested magnetic head assemblies by rotating said mounting base thereof with said pin or said hole of said mounting table as a rotation reference such that said one of said non-tested magnetic head assemblies is positioned along said predetermined one axis direction; transporting said one of said non-tested magnetic head assemblies positioned along said predetermined one axis direction, from said mounting table to said head clamp table by said handling robot by sucking said one of said non-tested magnetic head assemblies by said suction portion; and testing said magnetic head of said one of said non-tested magnetic head assemblies by positioning said suction portion using the position of said positioning pin as a reference, fitting said mounting hole thereof in said positioning pin, mounting said one of said non-tested magnetic head assemblies on said head clamp table, releasing the suction of said suction portion and clamping said one of said non-tested magnetic head assemblies on said head clamp table in said predetermined one axis direction.
