ABSTRACT:
According to one aspect and example, a method is provided for handling write protected storage devices. The method includes generating a read signal from a portion of a magnetic storage medium and determining if a modulation pattern is present in the read signal, the modulation pattern associated with an identification mark comprising a pattern of indicia associated with a recording layer of the magnetic storage medium. The identification mark indicates that the storage medium is a write protected storage device (e.g., a write-once-read-many “WORM” storage device or the like). If the storage medium is write protected, a media drive is restricted from write operations to the storage medium according to the particular write protected scheme, e.g., WORM, write append only, or the like.
