Disk drive mapping low frequency write addresses to circular buffer write zone |
摘要 |
A drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks. A random access write zone is defined on the disk comprising a first plurality of the data tracks, and a circular buffer write zone is defined on the disk comprising a second plurality of the data tracks. Write commands are received comprising logical block addresses (LBAs). First frequency and second frequency write LBAs are identified, where the second frequency is higher than the first frequency. Data associated with the first frequently write LBAs is stored in the circular buffer write zone, and data associated with the second frequency write LBAs is stored in the random access write zone. |
