Abstract
Employed is a structure for moving by a micro-actuator not a read/write element but an air-bearing surface pad. The air-bearing surface pad is arranged nearer to the leading end than the read/write element. This arrangement allows the read/write element portion to have a sufficient size, making it possible to mount the currently used read/write element and associated wiring structure. The individual adjustment of a flying height leads to the increased recording density. Moving the read/write element away from the disk during loading/unloading operations can enhance reliability.
