Abstract
A data storage device comprises recording heads and magnetic recording media. An initialization process is performed following a logical block address (LBA) remapping operation that remaps LBAs to physical locations on the media. The initialization process comprises initializing a write target LBA in response to a write command by writing data to a physical location on the media that is mapped to the write target LBA, receiving a read command to read data from a read target LBA, reading and returning data from the physical location on the magnetic recording media that is mapped to the read target LBA if the read target LBA has been initialized, and generating and returning a background data pattern if the read target LBA has not been initialized.
