Method for Wiring a Magnetic Head

This method eliminates wire bonding and looping to a head slider surfac when making electrical connections to a magnetic head 1 which is a part of a slider 2, as shown in Fig. 1.

With reference to Fig. 2, metal lands 3 are formed on one surface 4 of the slider for electrical contact with the head electrodes. The lands 3 are formed of permalloy and copper, which are deposited on the surface 4 with the formation of the head 1.

The lands 3 extend slightly beyond the surface boundary of the slider, as illustrated in Fig. 3. These extending ends of the lands are cut to expose the metal for connection to the wiring pattern 5 on the surface 6. The wiring pattern 5 is formed by deposition through a mask.

Subsequently, the wiring pattern is connected to an electrically conducting cable 7, supported on a head arm 8, for further connection to read/write circuitry, as shown in Fig. 2.
