SYSTEM, METHOD AND APPARATUS FOR STORAGE ARCHITECTURE FOR BIT PATTERNED MEDIA USING BOTH ERASE BAND AND SHINGLED MAGNETIC RECORDING

摘要

Storage architecture for bit patterned media uses both erase band and shingled magnetic recording. A hard disk drive may comprise a disk having bit patterned media with a plurality of data tracks arrayed in architecture pages having at least one of erase band mode (EBM), shingled mode (SM) and unallocated space. An actuator has a head for writing data to the data tracks of the bit patterned media. A control system monitors, reallocates and reconfigures the architecture pages from EBM, SM or unallocated space to a different one of EBM, SM or unallocated space to enhance performance of the hard disk drive.
