    摘要: A magnetic head assembly having a mounting base in which a mounting hole having a protruded peripheral edge is formed is easily mounted on a head clamp table positioning the magnetic head assembly by fitting the mounting hole on a boss pin or a receiving hole of a tray, with a pin or a hole on a mounting table and with a positioning pin on a head clamp table and positioning a suction collet with using a boss pin or a receiving hole of a tray as references, and sucking the mounting base of the magnetic head assembly by a handling robot without requiring high positioning accuracy.

    摘要: A magnetic disk certifier includes a defect detector circuit comprising a low-pass filter for extracting a low frequency component of the read-out signal, the low frequency component containing a signal component of the error, a signal generator circuit for generating a signal having a predetermined frequency lower than the frequency of the read-out signal, a synthesizer circuit for synthesizing an output signal of the low-pass filter and the signal outputted from the signal generator circuit and a comparator for generating an error signal by comparing the synthesized signal from the synthesizer circuit with a predetermined reference level.
