    Abstract: According to one embodiment, a method includes monitoring a plurality of parameters relating to operation of a tape drive to collect data from the operation of the tape drive, receiving a specification of one or more user-specified parameters to log during one or more collection windows, wherein the one or more user-specified parameters are specified from the plurality of parameters, logging at least some of the data collected from the operation of the tape drive to a memory during the one or more collection windows, wherein the at least some of the data collected is stored in a tape map comprising a plurality of fields, the plurality of fields including at least one histogram field, at least one per-channel field, and at least one per-channel indicator field, and dynamically overlaying one or more fields from the plurality of fields with data collected from the one or more user-specified parameters.

    Abstract: A system includes, according to one embodiment, a magnetic head having a plurality of write transducers configured to store data to tracks of a sequential access medium and a plurality of read transducers. Each read transducer is configured to read data from the sequential access medium after being written thereto by a corresponding write transducer. A first of the read transducers is aligned with a first of the write transducers, wherein the output of the first read transducer is produced during read-while-write. The system also includes a controller and logic integrated with and/or executable by the controller. The logic is configured to read, using the plurality of read transducers, encoded data from a plurality of tracks of the sequential access medium simultaneously. The logic is configured to determine that one or more tracks of the sequential access medium are dead within a sliding window and rewrite a set of encoded data from the one or more dead tracks to one or more live tracks in a rewrite area of the sequential access medium. Other systems, methods, and computer program products are described according to more embodiments.
