    • A magnetic recording system utilizing a magnetic recording disk. In some embodiments, one magnetic surface is utilized with an associated read/write transducer supported by a load beam. In other embodiments, the disk has a plurality of magnetic surfaces, each having an associated read/write transducer for reading and writing data in tracks in a plurality of zones and an associated load beam for supporting and positioning the respective read/write transducer at a plurality of locations above the respective surface. In one embodiment, the radial boundaries of the zones and read/write frequency for each zone are defined as a function of the number of available tracks on the recording surface. In another embodiment, the radial boundaries of the zones and read/write frequency for the zones are defined as a function of the read/write performance of the read/write transducer with respect to its associated magnetic surface. In a further embodiment, a read/write performance of the read/write transducer is determined, the recording performance of the magnetic surface is determined and the radial boundaries for each zones and the read/write frequencies for each zone are established as a function of the performances.

    • A novel method is used to remap tracks on a disk that contain a defect in a servo field so that a large seek discontinuity is not encountered. The method is applicable to both Class 2 and Class 3 defects. When a track with a Class 2 defect or adjacent tracks with a Class 3 defect are encountered, the tracks are skipped over in assigning physical track numbers to absolute track numbers. When a first defective track is encountered, the next track without a defect is assigned the physical track number that would have been assigned to the first defective track. As the remapping operation continues, each subsequent track with a Class 2 defect or adjacent tracks with a Class 3 defect is handled in a similar manner. The remapping operation is terminated when the number of mapped tracks is equal to the desired number of physical tracks n.
    • 一种新颖的方法用于重新映射包含伺服字段中的缺陷的磁盘上的磁道,从而不会遇到大的寻址不连续性。 该方法适用于2类和3类缺陷。 当遇到具有Class 2缺陷的轨道或具有Class 3缺陷的相邻轨道时,将轨道跳过以将物理轨道号分配给绝对轨道号。 当遇到第一个有缺陷的轨道时,没有缺陷的下一个轨道被分配给将被分配给第一缺陷轨道的物理轨道号。 当重新映射操作继续时,具有Class 2缺陷的每个后续轨道或具有Class 3缺陷的相邻轨道以类似的方式被处理。 当映射的轨道的数量等于所需的物理轨道数量n时,重新映射操作被终止。
