Abstract
A load/unload-type head suspension is capable of suppressing frictional coefficient variations. The head suspension has a head and a tab that is slid and guided along a ramp block in a read/write apparatus, to move the head away from a hard disk to a retract position. The tab is provided with microscopic irregularities to suppress frictional coefficient variations when the tab is guided along the ramp block. A center line average roughness (Ra) of the microscopic irregularities being greater than 0.2 μm or smaller than 0.6 μm.
