Abstract:
An apparatus, according to one embodiment, includes a magnetic head having servo readers of known pitch, a drive mechanism for passing a magnetic recording tape over the magnetic head, and a controller electrically coupled to the magnetic head. The controller is configured to measure, using signals from the magnetic head, a servo band difference at various locations along a length of the magnetic recording tape. The controller is also configured to cause storage of servo band difference information about the servo band difference measurements in association with the magnetic recording tape.

An apparatus configured to characterize a magnetic recording tape of a tape cartridge, according to one embodiment, includes a magnetic head having servo readers of known pitch, a drive mechanism for passing a magnetic recording tape over the magnetic head, and a controller electrically coupled to the magnetic head. The controller is configured to measure, using signals from the magnetic head, a servo band difference at various locations along a length of the magnetic recording tape of a tape cartridge. The controller is also configured to store the servo band difference measurements and/or derivatives thereof in association with the tape cartridge.
Abstract:
A method for characterizing a magnetic recording tape of a tape cartridge, according to one approach, includes measuring, using a magnetic head having servo readers of known pitch, a servo band difference at various locations along a length of a magnetic recording tape of a tape cartridge. The servo band difference measurements and/or derivatives thereof are stored in association with the tape cartridge. This procedure creates a characterization of the magnetic recording tape that is useful for assessing aging of the magnetic recording tape, as well as improving subsequent reading and/or writing operations.
Abstract:
A system according to one embodiment includes a tape library and a tape drive coupled to the tape library. In response to determining that at least one special operation may be performed, the tape library sends a first notification that the tape drive is to remain in a not ready state. The tape library mounts the tape cartridge in the tape drive after determining that at least one special operation may be performed. A method according to one embodiment includes sending a first notification that a tape drive is to remain in a not ready state in response to determining at least one special operation may be performed by said tape drive upon mounting of a tape cartridge therein. The tape cartridge is caused to be mounted in the tape drive after determining that at least one special operation may be performed.

Abstract:
A computer-implemented method according to one embodiment includes receiving at a storage drive, from a host, a data request, implementing the data request at the storage drive, utilizing a streaming mode, and returning, by the storage drive, a confirmation to the host, in response to implementing the data request at the storage drive utilizing the streaming mode.
Abstract:
A method according to one embodiment includes receiving a request to store data on media, and generating a data key. An encryption encapsulated data key is generated using the data key. A session encrypted data key is generated using the data key. The encryption encapsulated data key and session encrypted data key are provided for use in writing encrypted data to the media. A method according to another embodiment includes receiving a request to read data from media, and receiving an encryption encapsulated data key. The encryption encapsulated data key is processed to obtain a data key. A session encrypted data key is generated using the data key. The encryption encapsulated data key and session encrypted data key are provided for use in reading the encrypted data from the media.
Abstract:
In one embodiment, a product includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. An indicator of a physical position on the magnetic medium that corresponds to an end of the encrypted data is stored on the product. A product according to another embodiment includes a magnetic medium having written thereon data in a data track. The data includes encrypted data written over unencrypted data. A portion of the unencrypted data is located before the encrypted data on the medium. An indicator of a physical position on the magnetic medium that corresponds to a beginning of the encrypted data is stored on the product.

Abstract:
A storage system includes a plurality of drives that write and read data to and from removable storage media communicatively connected to a storage controller. The storage controller receives comprehensible data and divides the comprehensible data into the plurality of data segments comprising the plurality of data units, manipulates one or more of the plurality of data units within each data segment to form the plurality of unintelligible data segments, generates a decoding key based upon the division and the manipulation, and sends each respective unintelligible data segment to the plurality of drives to store upon the removable storage media. The comprehensible data includes a sufficient number of data units arranged in an order of inherent meaning and the unintelligible data segments include an insufficient number of data units to be comprehensible arranged in an order such that the unintelligible data segments are incomprehensible.
