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.

Abstract: A tape cartridge housing allowing for both pre-shell closure and post-shell closure insertion of an auxiliary memory unit is provided. A flexible tape cartridge housing allows a manufacturer of tape cartridges to select whether to incorporate an auxiliary memory unit into the tape cartridge during the manufacturing process while a tape cartridge is still not fully assembled, during the end of the manufacturing process when the tape cartridge top and bottom shells have been combined, or after the manufacturing process when the tape cartridge is ready for operation.

Abstract: A buckler assembly in a tape drive is used to connect a drive leader to a cartridge leader, where the drive leader is connected to a take-up reel and the cartridge leader is connected to a magnetic tape in a tape cartridge. The buckler assembly includes a retainer member that receives the drive leader to be connected to the cartridge leader. The buckler assembly also includes a sensor assembly disposed adjacent to the retainer member that detects the presence of the drive leader.
