Abstract
A method for correcting errors when writing a stream of data to a data, received from a host apparatus, to a magnetic tape data storage medium comprises: partitioning the stream of digital data into a plurality of fragments; writing the plurality of fragments to the data storage medium; reading the plurality of fragments from the data storage medium; checking whether each of the read fragments are correct; assigning each of the correct read fragments to only one of a plurality of groups of fragments; counting a total number of correct read fragments within each of the plurality of groups of fragments; and if the total number of correct read fragments within any of the plurality of groups of fragments is less than the threshold number of correct read fragments then the step of writing the plurality of fragments to the data storage medium is repeated.
