A method for reducing data loss includes a first computing step for computing an intermediate result for each redundancy information entity of a redundancy set by processing respectively associated data information entities of a given data set on at least two main diagonals of a parity check matrix representing an error correction coding scheme. The method further includes a second computing step for computing the information content of the respective redundancy information entity dependent on the respective intermediate result.

Creating an error correction coding scheme and reducing data loss

A storage device and a method for scanning a storage medium. A storage medium for storing data in the form of marks is scanned by an array of probes for mark detecting purposes in a scanning mode. The storage medium has fields with each field to be scanned by an associated one of the probes. At least one of the fields has marks representing operational data for operating the scanning mode. Scanning parameters are computed from the operational data and the scanning mode is adjusted according to the computed parameters.
