An experiment study of fly height was performed to observe how the head-disk spacing after loading-unloading the head from the ramp onto the disk on the spin-stand testing. The fly height of write and read operation were analyzed by calculated from the power applied. The heater resistance of write and read were collected during test. Results of the test 190,000 cycles of loading/unloading showed, the fly height of write increased more than the read. The fly height of all heads showed increasing trend. Observing the lube pick up on head and accumulation lube on the disk about 20%. The heater resistance of write and read were quite standing.
