Popis:	Head alignment equipment for floppy disk drive (FDD) was developed to elevate the quality of FDD. The equipment adjusts the position of upper magnetic head to lower magnetic head relatively with micro meter order accuracy. Prior to the development, the structure of FDD head assembly was improved. To prevent the slip out of upper head in time of screwing, gate shaped plate spring called “hold spring” was added between screws and the fixed part. Size parameters of “hold spring” was decided by combination of finite element method analysis with experiment, and the slip out of the head was decreased to 1/5. The feature of the equipment is a precision movement stage. To avoid the backlash, the stage, is made of 3 axis flexure pivoted levers with displacement reduction mechanism in one body. Owing to these technical settlements, automatic precision alignment of head position was established.
