ABSTRACT:
A multiple frequency zoned disk storage device in which data is read from and/or written to the disk at two or more discrete disk velocities is disclosed. The disk storage device includes a low power mode where information is read/written from/to the disk while the disk velocity is reduced to conserve power. The allocation track locations into zones on the drive reduces the number of zone bit frequencies the storage device must handle.
