Patent ID: 7187514

Claim:
A magnetic disk drive, comprising: a magnetic head slider ( 1 ) mounted thereon with a magnetic read/write element ( 20 ) to read and write information; a suspension ( 4 ) comprising a plate spring ( 9 ) of a thin plate shape for adhering to and supporting said magnetic head slider ( 1 ), a flexible circuit ( 8 ) and a load beam ( 10 ); a magnetic disk ( 2 ) for holding information; rotation drive ( 16 ) of said magnetic disk ( 2 ); and an actuator mechanism ( 13 ) for moving a magnetic head assembly ( 3 ) along the information recording surface of said magnetic disk ( 2 ), said actuator mechanism comprising said magnetic head slider ( 1 ) and said suspension ( 4 ), wherein said magnetic disk drive further comprises means for changing a flying height of said magnetic head slider ( 1 ) with respect to said magnetic disk ( 2 ) according to temperature in said magnetic disk drive, and means for particularly decreasing the flying height from the flying height at a room temperature of 25° C. when the temperature is lower than the room temperature and increasing the flying height from the flying height at the room temperature when the temperature is higher than the room temperature.
