Title: Method for measuring floating gap in magnetic head
Inventor: KATSUTA YASUO
IPC: G11B21/21
Filed: 1989-05-31
Abstract: PURPOSE:To make a measurement correct and easy by utilizing data of correlations when the relative speed of a magnetic disk and a magnetic head is low and high and converting the measured value of a floating gap when the relative speed is high to the value when the speed is low. CONSTITUTION:The floating gaps when the relative speed of the magnetic head and magnetic disk is low and high are measured beforehand as to plural cases by a light with a short wavelength and by a light with a long wavelength, respectively, values a1 and b1 and values a2 and b2 corresponding in the same magnetic head are plotted, an area W to contain the most number of respective points 1, 2,... to be plotted is decided, a center line C of the area W is specified, and the corresponding data of the floating gaps when the relative speed is low and high are prepared. Next, at the time of the measurement of a device to be measured, the floating gap is measured as the relative speed to be the same as the time of the high speed when the corresponding data are obtained, and the value when the relative speed is low in the same way as a product and the floating quantity is small is obtained by the conversion based on the value of the measured floating gap.

Abstract: PURPOSE:To take a test under invariably normal measurement condition by connecting a diode between one terminal of a switch means which is connected at the other terminal to a signal line and a check signal line to which the check signal of the switch means is connected. CONSTITUTION:When a test equipment body 1 is put by temporary testing operation while a contact probe 5 is brought into contact with a diffused layer 7b, the switch means 4 is turned off. At this time, the main body 1 applies a forward voltage tothe diode 7. When the switch 4 is normal and off at this time, no current is detected at a monitor point 6 and a fine leak current is detected at a monitor point 10.
