摘要： This disclosure deals with an optical disk recorder/player (drive) of the type that receives a removable disk for signal exchanging operations. Once a disk is inserted into the drive, the rotation of the disk begins a period of accelerating rotational speed called spin up. During spin up, the focus and tracking systems of the drive are calibrated. Once the disks reach a desired operating rotational speed, a menu is provided for determining when to calibrate a laser in the drive for recording operations. Such writing or recording calibration of the laser occurs at different times in accordance with the types of signal processing functions to be performed with respect to the particular disk. Description includes a media library in which a plurality of optical disk drives are controlled in a manner for minimizing access times to any optical disk within the media library.

摘要： Provided are a computer program product, system, method, and data structure for using variable length code tables to compress an input data stream to a compressed output data stream. If a number of consecutive data units in the input data stream match the number of consecutive data units in a history buffer of previously received data units in the input data stream, a copy pointer symbol is generated indicating the copy pointer symbol referencing previously received data units in the history buffer and indicating a location of a start of the consecutive data units in the history buffer. A determination is made from a variable length code table of an encoding of the number. Indication is made in the generated copy pointer symbol the determined encoding of the number and the copy pointer symbol is outputted in the compressed output data stream.

摘要： Methods, logic, apparatus and computer program product write data, comprising less than a full Data Set, to magnetic tape. Data is received from a host, a do-not-interleave command is issued and C1 and C2 ECC are computed. Codeword Quad (CQ) sets are then formed. At least one CQ set of the Data Set is written to a magnetic tape in a non-interleaved manner and a Data Set Information Table (DSIT) is written to the magnetic tape immediately following the at least one written CQ set. An address transformation may be used to cancel interleaving. Writing a CQ set may include writing a plurality of contiguous instances of the CQ set to the magnetic tape to maintain the effectiveness of ECC capability.

摘要： A tape system is provided with an encryption capable tape drive and an encryption enabled tape drive device driver for the encryption capable tape drive. The encryption enabled tape drive device driver functions as a proxy which connects the encryption capable tape drive to a key manager which serves keys to the tape drive. When the encryption capable device driver causes a command to be sent to the drive, the tape drive is configured to respond with a message that is intended for a key manager such as an External Key Manager (EKM). The encryption capable device driver recognizes that this is a message intended for the EKM and forwards that message to the EKM (e.g., via an Internet Protocol (IP) connection). The EKM then responds to the key request by issuing a new key (for a new cartridge which is to be written from beginning of tape (BOT)) or an existing key (for a cartridge which needs to be read). The device driver connects all EKM responses to the encryption capable tape drive and the EKM from which the encryption capable tape drive obtains its keys.

摘要： A method, system and program are provided for enabling access to encrypted data in a storage cartridge by wrapping the data key used to encrypt the data with one or more encryption keys (e.g., a public key from a public/private key pair) to form one or more encryption encapsulated data keys (EEDKs) and then storing the EEDK(s) on the storage cartridge along with the encrypted data in one or more location that are distinct from the encrypted data. The encrypted data may be decoded by retrieving the EEDK from the storage cartridge, decrypting the EEDK with a decryption key (e.g., the private key from the public/private key pair) to extract the underlying data key, and then using the extracted data key to decrypt the encrypted data. By storing the EEDKs separately from the encrypted data, the EEDKs may be updated independently of the corresponding encrypted data.

摘要： An automated data storage library accesses data stored on storage media contained in cartridges in response to commands from an external host. The cartridges may include cartridge memory and a component in the library may include a cartridge memory interface for reading data from and/or writing data to the cartridge memory. When a cartridge is to be stored in the library, the library modifies the contents of the cartridge memory, or the contents of the storage media such that the data stored on the cartridge becomes inaccessible, thereby preventing access to the data outside of the library. To perform an authorized access, the library restores the contents of the cartridge memory or the storage media. Alternatively, the library provides a correction or correction algorithm to the drive to allow access to the data stored on the storage media without removing the access protection of the storage media. The cartridge memory or storage media may also or alternatively include an identifier which permits access to the data only by the identified physical and/or logical library(s).

摘要： A method of reducing data expansion during data compression is provided that allows the coding scheme used to compress data to be swapped between two or more coding schemes. Specifically, a coding window is provided that allows analysis of the compression potential of data within the coding window. The data within the coding window then is analyzed to determine the compression potential of the data. If the compression potential of the data exceeds a first predetermined value, the coding scheme used to compress the data within the coding window is swapped from one coding scheme to another. Preferably the first predetermined value is programmable and is related to the bit cost required to swap back and forth between coding schemes. The two preferred coding schemes are ALDC Lempel-Ziv 1 coding and a pass-through coding scheme wherein raw data is passed unencoded.
