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.
A magnetic disk drive comprising a magnetic disk, a rotary mechanism for the magnetic disk, a slider flying near a surface of the magnetic disk with a predetermined gap therebetween due to an pneumatic bearing effect produced by an air-bearing surface pad, a read/write element mounted on the slider, and a mechanism for supporting and positioning the slider in a radial direction of the magnetic disk, wherein a movable portion is formed on a side of the slider where the read/write element is installed, the movable portion being separated by a cut from a read/write element portion, and at least one air-bearing surface pad is provided on the movable portion.
A method of controlling a magnetic disk drive that causes a slider to fly near a surface of a magnetic disk with a predetermined gap therebetween due to a pneumatic bearing effect produced by an air flow, which is generated by a rotation of the magnetic disk and acts on an air-bearing surface pad provided on the slider, reads and writes information to and from the magnetic disk by a read/write element mounted on the slider, the method comprising the steps of separating by cuts a center of a trailing end portion, with respect to a disk rotation direction, of the slider from both side portions of the center, providing the read/write element to the center of the trailing end portion, providing a drive mechanism on each of the separated portions to drive the separated portions individually, and moving both the side portions when performing read/write operations.
