| 1. A magnetic head tester comprising:
a magnetic disk for recording information as signals;
a rotative driving mechanism to rotate the magnetic disk;
a magnetic head for writing signals to and reading signals from the magnetic disk;
an HGA (head gimbals assembly) supporting the magnetic head above the magnetic disk; and
an HGA driving mechanism to drive the HGA;
wherein a VCM actuator employed in a production HDD (hard disk drive) is used for driving the HGA, an electronic circuit board
employed in the production HDD is used for driving the VCM actuator, and an actuator arm included in the VCM actuator is provided
with an automatic HGA fixing mechanism capable of detachably fixing the HGA to the actuator arm;
wherein the HGA fixing mechanism includes a holding spring disposed on an HGA holding part of the actuator arm and a stopper
disposed on the actuator arm the holding spring presses a mount plate included in the HGA against the stopper to fix the HGA
to the actuator arm, and the holding spring is pressed mechanically to release the HGA.
