摘要： 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.

摘要： A suspension for disc drive has a load beam, a flexure, and a slider. The slider is mounted on a tongue portion of the flexure. When a disc rotates, air flows from an air inflow end (leading side) toward an outflow end (trailing side), whereupon an air bearing is formed between the disc and the slider. A dimple is provided on the distal end portion of the load beam. The slider is supported by the dimple so as to be swingable in a pitch direction and a roll direction. The dimple is formed in a position shifted to the trailing side from the center of the slider. The shorter the length of the load beam, the greater the amount of the shift is.
