ABSTRACT:
A method has been discovered for recovering data recorded on magnetic recording tape wherein adjacent layers have become adhered after long storage times, even at recommended storage conditions. The method comprises localized heating of the tape in an amount sufficient to break hydrogen (physical) bonding between the binder and the film backing. A continuous tension is applied to the tape, while withdrawing it from the spool to break residual adhesion. The spool is turned at a rate of speed sufficient to carry away heat so that the film does not reach the heat distortion temperature.
