Abstract:
1. A method for operating a magnetic tape data storage system, said system comprising at least one magnetic tape data storage drive configured to handle at least one magnetic tape data storage cartridge comprising a magnetic tape data storage media and accompanying cartridge memory, said magnetic tape data storage media comprising a plurality of servo bands extending in a longitudinal direction of said magnetic tape data storage media, said servo bands separated by data bands, comprising the steps of: sensing two said servo bands, each at opposite sides of a data band, of said magnetic tape data storage media of a magnetic tape data storage cartridge; responding to at least one servo detection error signal of one of said two servo bands of said sensing step, to set an edge stress signal to said accompanying cartridge memory of said magnetic tape data storage cartridge; inspecting a cartridge memory of a magnetic tape data storage cartridge for a set said edge stress signal; and if said edge stress signal is set, preventing normal write operations such that only read operations are allowed with respect to said inspected magnetic tape data storage cartridge.
