Magnetic head device and recording medium drive |
摘要 |
This invention relates to a magnetic head device and a disk drive, which are suitable for application to a mass-storage floppy disk drive or the like. A first and a second rail are provided on the disk side in projected form on a slider of each of magnetic head elements 20 so as to extend in a tangential direction R of a track of the disk and be parallel with each other. A head chip for recording and reproducing data in a state of being in contact with a recording surface of the disk and in a standard recording density is provided substantially in the central position of the first rail. Another head chip for recording and reproducing data in a state of being levitated from the recording surface of the disk and in a high recording density is provided in a position on the rear side of the second rail 26b with respect to the tangential direction R of the track. A width of the first rail of each magnetic head element is narrower than a width of the second rail thereof. The slider is inclined and levitated so that the second rail approaches the recording surface of the disk.
