    Abstract: A tape reader is provided that reads data from a tape without requiring specific alignment. The tape reader may include a reader head comprising a sensor array with a plurality of sensors that detect the data independent of the track within which the data is stored. Multiple sensors may detect data in each track instead of a single, dedicated sensor for each track. The sensor array may comprise multiple sensors in multiple dimensions, such as perpendicular to the movement of the tape or in parallel to the movement of the tape, including serpentine linear recording formats where the sensors may be in a matrix positioned at various angles from horizontal to vertical.

    Abstract: A write head for writing a servo pattern to a magnetic tape medium includes a first coil configured to generate a first magnetic flux when applying an electric current to the first coil, a second coil configured to generate a second magnetic flux when applying an electric current to the second coil, and a pole piece structure configured to guide the generated magnetic flux. The pole piece includes a first ring structure for guiding the first magnetic flux, a second ring structure for guiding the second magnetic flux, and a common section of the first and the second ring structure which common section is arranged between the first coil and the second coil. The write head further includes a section containing a gap in each of the first ring structure and the second ring structure. The magnetic flux is oriented in opposite directions across the two gaps.

    Abstract: A magnetic tape medium includes at least one servo band along a longitudinal extension of the tape medium which at least one servo band comprises servo patterns organized in servo frames for supporting to determine positional information. At least one of the servo frames includes a first burst comprising at least two servo stripes inclined at a first angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, followed by a second burst including at least two servo stripes inclined at a second angle with respect to a direction orthogonal to the longitudinal extension of the tape medium, which second angle is different from the first angle. At least one of the stripes of the first burst has a first magnetic polarity and at least one of the stripes of the second burst has a second magnetic polarity different from the first magnetic polarity.

    Abstract: A system and method for selective recording of information uses sequential pattern matching of statistical vectors which characterize incoming time-based information to identify previously marked information within an incoming information stream. The system and method generate a signal to control a recording device to either elide the previously marked information from the recording, or to begin recording once the previously marked information is identified, depending upon the current mode of operation. The system and method may be utilized to omit recording of unwanted information, such as commercials in a television broadcast, or to automatically locate desired information on any of a number of available information channels without a priori knowledge of the occurrence time or channel of the information.

    Abstract: A method of controlling relative motion of a data storage medium on which data is stored in data groups comprising tracks extending across the storage medium and a rotatable transducer for reading data from the storage medium includes determining from the data groups a start reread data group at which a data reread process is to start following detection of a read error condition in a preceding data read process. The method also includes obtaining a reread track reference value for use in controlling that relative motion during the data reread process using a track reference value difference stored in at least one track of at least one data group that is to be reread during the data reread process and a track reference value that was used in controlling that relative rotation during the preceding data read process.
