    Abstract: A sequential data storage medium, comprising a sequence of plurality of servo patterns that provide lateral position information and longitudinal position information, wherein each of the plurality of servo patterns comprises a first burst comprising a first plurality of pulses, a second burst comprising a second plurality of pulses, a third burst comprising a third plurality of pulses, and a fourth burst comprising a fourth plurality of pulses. The spacings between the first plurality of pulses, in combination with the spacings between the second plurality of pulses, encode a first bit without affecting the recovery of lateral position information. The spacings between the third plurality of pulses, in combination with the spacings between the fourth plurality of pulses, encode a second bit without affecting the recovery of lateral position information. The sequence of plurality of servo patterns comprises a sequence of the first bits and a sequence of the second bits to form an error-correction codeword providing error-correction capability.

    Abstract: A magnetic tape drive system (20) records a directory block (CL) at a predetermined position on tape (22). The directory includes a data block number of the data block recorded at an end of each track. Upon receipt of a command to locate a target data block recorded on tape (22), a processor (102) directs a transport controller (82) to position a read element (30R) at the predetermined position on tape (22) for reading the directory. The processor (102) compares the target block numers with the data block numbers stored and in response thereto causes a positioner (74) to position the read element with respect to the tape (22) width so as to read the track upon which the data block having the target data block number is recorded.

    Abstract: The invention relates to a method of implicitly partitioning the storage space available on a storage medium, to a storage medium for storing user data and to a recording device for storing user data on a storage medium. In order to limit the mount/unmount time of a volume like a UDF volume on a magnetic tape for ADR and to limit overall seek times during reading it is proposed according to the invention: a)storage space available for storage on the medium is divided into a directory region and a data region, b) metadata are stored in the directory region, c) user data are stored in the data region being implicitly subdivided into data sub-regions, d) file set data for user data stored in a data sub-region are stored in a corresponding directory sub-region being assigned to this data sub-region, and e) borders and size of data sub-regions are variable.
