Abstract
Methods, magnetic tape data storage drives, data storage systems, and magnetic tape data storage cartridges. A system having at least one magnetic tape data storage drive is configured to handle a magnetic tape cartridge comprising a magnetic tape data storage media and accompanying cartridge memory. The magnetic tape media comprises a plurality of longitudinal servo bands, the servo bands separated by data bands. Two servo bands, each at opposite sides of a data band are sensed. In response to at least one servo detection error signal of one of the two servo bands, an edge stress signal is set to the cartridge memory of the magnetic tape cartridge. Then, for example, after reloading the cartridge, the cartridge memory is inspected for a set edge stress signal; and, if the edge stress signal is set, only read operations are allowed with respect to the inspected magnetic tape data storage cartridge.
