A combination includes a family of cartridge drives () including a first cartridge drive and a second cartridge drive, and a family of cartridges () including a first cartridge and a second cartridge. The first cartridge drive includes a first protrusion pattern (), and the second cartridge drive includes a second protrusion pattern () that is different than the first protrusion pattern (). The first cartridge includes a first recess pattern () that receives the first protrusion pattern () thereby allowing full insertion of the first cartridge into the first cartridge drive. The second cartridge includes a second recess pattern () that receives the second protrusion pattern () thereby allowing full insertion of the second cartridge into the second cartridge drive. The second protrusion pattern () can impede full insertion of the first cartridge into the second cartridge drive. Further, the first protrusion pattern () can impede full insertion of the second cartridge into the first cartridge drive. The protrusion patterns () include protrusions () each having a protrusion length (A-D) which can vary between cartridge drives (). The cartridge () includes a cartridge housing () having a cartridge rear wall () and a plurality of cartridge side walls (). The recess patterns () can be positioned along one or more of the cartridge side walls () and/or the cartridge rear wall (). The cartridge () includes a cartridge housing () that defines a housing interior (). The recess pattern () can be configured to not allow access into the cartridge interior ().

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.

Media cartridge protective case

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.

Mam assembly process and features

Shipping tray for multiple cartridges

A cartridge assembly () includes a cartridge () and a cartridge retainer (). The cartridge () includes a reel () having a rotational axis () and a flange (). The cartridge () also includes a cartridge housing () that rotatably secures the reel (). The cartridge housing includes one or more interior surfaces (). The reel () is adapted to tilt relative to the cartridge housing (). The cartridge housing () includes a plurality of ribs () each having a chamfer (). The ribs () can be disposed on an upper housing section () and/or a lower housing section () of the cartridge housing (). The reel () has a contact tilt angle &#x3b8;relative to the interior surface (), and at least one of the chamfers () has a chamfer angle &#x3b8;relative to the interior surface () that is substantially similar to the contact tilt angle &#x3b8;. The flange () contacts the chamfer () so that the flange () is substantially parallel with the chamfer (). The cartridge () can also include a positioner rib () for laterally positioning the reel (). Further, a flange edge () of the flange () does not contact the cartridge housing () when the reel () tilts. The cartridge assembly () includes a reel positioner () that biases the reel () of the cartridge () toward the upper housing section () of the cartridge housing () while the cartridge () is retained within the cartridge retainer ().

Cartridge housing for inhibiting damage to recording media

Methods and apparatuses for identifying a single reel tape cartridge format, in a single reel tape handling device, from a plurality of available formats. According to one aspect of the invention, cartridge identification information is provisioned on a single reel tape cartridge leader. The cartridge identification information is detectable by the tape handling device and usable to identify a format of the tape cartridge from a plurality of available formats. The cartridge identification information includes at least one feature on the tape cartridge leader having characteristics indicative to the tape handling device of the format of the tape cartridge presented to the tape handling device.

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.
