ABSTRACT:
A guide pin-manufacturing method includes the steps of plating a stepped cylindrical main portion (which is formed of brass or another non-magnetic material) with a hard, thick chromium plating layer by rotating the main portion in a plating liquid, forming a large number of minute grooves in the entire surface of the main body such that the grooves extend in the circumferential direction of the main body, and forcibly fitting two collars around the respective ends of the main portion. By execution of these steps, a guide pin to be arranged inside a data cartridge is manufactured. The guide pin arranged in the data cartridge guides the magnetic tape such that the magnetic tape travels in a stable manner.
