Abstract:
A recording medium drive comprising:a magnetic head device having first and second head portions disposed in an opposing relationship so as to interpose a recording medium therebetween, a magnetic head element, which constitutes each of the first and second head portions, including; a slider; first and second rails provided on the slider, the first and second rails protruding toward the recording medium, extending in a tangential direction of a track of the recording medium and parallel with each other; a first head chip provided in the first rail and configured to record and reproduce data in a state of being kept in contact with a recording surface of the recording medium; and a second head chip configured to record and reproduce data in a state of being levitated from the recording surface of the recording medium and in a predetermined density, said second head chip being provided in a position on the rear side of said second rail with respect to the tangential direction of the track; wherein the width of said second rail is narrower than that of said first rail such that the slider is levitated to an inclined state with an interval between the second rail and the recording medium being less than an interval between the first rail and the recording medium; and wherein said first and second rails of said magnetic head element constituting said first head portion are provided so as to be opposite to said second and first rails of said magnetic head element constituting said second head portion; a record processing circuit for generating record data to be recorded on the recording medium by said magnetic head device; and a reproduction processing circuit for processing reproduction data provided from the recording medium by said magnetic head device.
