摘要： A uniformly distributed magnetic recording medium is carried on or in an initially fluidizable support. During or after magnetically writing information upon the medium, the support is changed to a fluidized state, sufficient to permit some physical translational movement of the medium in localized areas corresponding in pattern to characteristic magnetic non-uniformities caused in medium by the magnetic writing. The support is then set or otherwise converted to a state in which such movement is no longer possible. Thereafter, even if the medium is degaussed, the now set non-uniformities in physical distribution of the recording medium, will permit the information that had been magnetically written, to continue to be read e.g. by magnetic analysis of the medium..
