摘要： The technology disclosed herein enables automatic implementation of a physical barrier to protect access to data on removable storage media. In a particular embodiment, a method provides determining that the item moved into a storage position using an automatic transfer mechanism and determining that a condition for protecting the item is satisfied. Upon determining that the condition is satisfied, the method provides implementing a physical barrier that prevents the automatic transfer mechanism from removing the item from the storage position.

摘要： A servo system for a magnetic tape storage system includes a magnetic tape (550) including a first servo band (573), and a first data band (575). An auxiliary servo pattern (575A) is embedded within the first data band (575). The auxiliary servo pattern (575A) is modified to generate an updated auxiliary servo pattern (688A) during a writing pass as data is being written to the first data band (575). The servo system can further include a magnetic tape drive (326) including a head assembly (456) having (i) a first write head (482) that writes data to the magnetic tape (550) as the magnetic tape (550) moves relative to the head assembly (456) in a first tape direction, (ii) a second write head (484) that writes data to the magnetic tape (550) as the magnetic tape (550) moves relative to the head assembly (456) in a second, opposite tape direction, and (iii) an auxiliary servo reader (487) positioned in a shadow of one of the first write head (482) and the second write head (484).

摘要： A method for providing enhanced readability of data written to a magnetic tape, includes the steps of (i) writing data to a first tape partition using a tape drive, the data being written under a first dimensional stability condition; (ii) monitoring an ambient dimensional stability condition with a condition monitor to determine if the ambient dimensional stability condition has moved at least a predetermined threshold value from the first dimensional stability condition toward a preferred dimensional stability condition; and (iii) replicating the data to a second tape partition with a data replicator when it has been determined that the ambient dimensional stability condition has moved at least the predetermined threshold value from the first dimensional stability condition toward the preferred dimensional stability condition.

摘要： Apparatus, methods, and other embodiments associated with object synthesis are described. One example apparatus includes logic for identifying a block in a data de-duplication repository and for identifying a reference to the block. The apparatus also includes logic for representing a source object using a first named, organized collection of references to blocks in the data de-duplication repository and logic for representing a target object using a second named, organized collection of references. The apparatus is configured to synthesize the target object from the source object. Since synthesis may be complicated by edge cases, the apparatus is configured to account for conditions including a block in the target object needing less than all the data in a source object block, data to be used to synthesize the target object residing in a sparse hole in a data stream, and the target object needing data not present in the source object.

摘要： A magnetic tape drive for writing data to a magnetic tape that includes a first data band, a second data band, and a servo band that is positioned between the first data band and the second data band, each of the data bands including a plurality of wraps including a first wrap and a last wrap, includes a drive controller and a tape head. The drive controller defines at least a first partition and a second partition within the magnetic tape. The tape head is configured to write data to the first partition of the magnetic tape and subsequently write data to the second partition of the magnetic tape. The drive controller defines an end of the first partition to be directly after the last wrap of the first data band. The drive controller controls the tape head to write data to all of the plurality of wraps of the first data band.

摘要： A state evaluator for use in a media library includes a housing and a first camera that is coupled to the housing. In some embodiments, the state evaluator can also include one or more of a light assembly, an indicator assembly to indicate different conditions associated with the state evaluator, an input assembly, an internal power source, and a power module. The power source can be rechargeable and/or removable. The first camera can capture visible light, infrared light, and/or ultraviolet light images. The light assembly can emit visible light, infrared light, and/or ultraviolet light. The state evaluator can have a high intensity light source and can communicate with a host system. The state evaluator can also include a second camera that can be coupled to the housing.

摘要： Embodiments disclosed herein provide systems, methods, and computer-readable media to implement an object store with removable storage media. In a particular embodiment, a method provides identifying first data for storage on a first removable storage medium and designating at least a portion of the first data to a first data object. The method further provides determining a first location where to store the first data object in a first value store partition of the first removable storage medium and writing the first data object to the first location. Also, the method provides writing a first key that identifies the first data object and indicates the first location to a first key store partition of the first removable storage medium.

摘要： A climate controller for a media library having a library interior includes one or more of a temperature sensor, a temperature controller, a humidity sensor, and a humidity controller. The temperature sensor senses an inside temperature within the library interior. The temperature controller is positioned within the library interior. The temperature controller controls the temperature within the library interior based at least partially upon the temperature information. The temperature controller can include one of a temperature increaser and a temperature decreaser. The humidity sensor senses an inside humidity within the library interior and generates humidity information. The humidity controller is positioned within the library interior. The humidity controller controls the humidity within the library interior based at least partially upon the humidity information. In various embodiments, the humidity controller cooperates with the temperature controller to control climate conditions within the library interior based on climate conditions outside of the library interior.

摘要： A tape drive for use with a magnetic tape including two spaced apart servo tracks and a first data track includes a tape head, an actuator assembly, and a controller. The tape head includes two spaced apart servo elements that are each configured to read one of the two servo tracks, and a first read/write element that is configured to one of read data from and write data to the first data track. The tape head is positionable at a base head rotation angle relative to transverse to the length of the magnetic tape. The actuator assembly is configured to selectively rotate the tape head relative to the magnetic tape. The controller controls the actuator assembly to selectively rotate the tape head relative to the magnetic tape from the base head rotation angle to an adjusted head rotation angle that is different than the base head rotation angle based solely on servo information from the two servo elements reading the two servo tracks.
