摘要： Embodiments of the present invention help to improve the capacity and the performance of a disk drive device. According to one embodiment, a data track pitch is set to each recording surface. The recording surfaces are divided into bands. A hard disk drive (HDD) sequentially moves a head to an adjacent data track in a band and performs a head switch at the band end in its data accessing. On a recording surface, the number of data tracks in each band is variable; and each band is constituted by different number of data tracks as necessary. The number of data tracks in each band is set so that the radial position of the band end comes close to the radial position of the corresponding band end on another recording surface. Accordingly, even if the recording surfaces have different variation rates of the data track pitch in the radial direction, increase in process time due to head switches can be suppressed.
摘要翻译：本发明的实施例有助于提高磁盘驱动装置的容量和性能。根据一个实施例，将数据轨道间距设置到每个记录表面。记录表面被分成带。硬盘驱动器（HDD）顺序地将磁头移动到频带中的相邻数据磁道，并在其数据访问中在频带端执行磁头切换。在记录表面上，每个频带中的数据轨迹数是可变的; 并且每个频带由必要的不同数量的数据轨道构成。每个带中的数据轨道的数量被设置为使得带端的径向位置接近另一个记录表面上相应带端的径向位置。因此，即使记录面在径向方向上具有不同的数据磁道间距的变化率，也可以抑制由磁头开关引起的处理时间的增加。
