Abstract:
1. A magnetic disk drive comprising: a housing having a base; an actuator arm mounted on a pivot for pivotal motion on said base; a suspension having a base end fixed to a tip end of said actuator arm; a head slider having at least two electromagnetic transducers mounted at a tip end of said suspension, wherein each of the at least two electromagnetic transducers is a recording and reading electromagnetic transducer and the electromagnetic transducers accept writing signals and supply reading signals; a magnetic disk accommodated for rotation in said housing; and controlling means for performing changeover control between said at least two electromagnetic transducers, wherein said head slider has an air inflow end, an air outflow end, an inner side face, an outer side face, a first electromagnetic transducer having a first end and a second end, the first end being closer to said inner side face than the second end, and a second electromagnetic transducer having a third end and a fourth end, the fourth end being closer to said outer side face than the third end, said first electromagnetic transducer being inclined in a direction in which the first end is closer to said air outflow end than the second end, said second electromagnetic transducer being inclined in a direction in which the fourth end is closer to said air outflow end than the third end, and said controlling means performs the changeover control such that a data region of said magnetic disk is virtually divided at a central portion of said magnetic disk into two regions and the inner side data region is taken charge of by said first electromagnetic transducer while the outer side data region is taken charge of by said second electromagnetic transducer.
