Abstract
In accordance with an illustrative embodiment of the present invention, a magnetic tape which has seismic data thereon and which has been stored for so long that stiction is a problem is temporarily placed in an environmentally sealed room and subjected to a temperature of about 140.degree. F. and a relative humidity of 20% or less for about 48 hours. After removal from the room and cooling down to ambient temperature of about 70.degree. F. in the presence of relative humidity of about 50%, the tape is cleaned and retensioned on a reel. The data then can be read out onto another media with recovery of practically 100% of the seismic data.
Claims7
A method of processing a magnetic tape having stiction to enable the recovery of data thereon, comprising the steps of:
- placing said tape in a controlled environment under a selected range of elevated temperatures and reduced relative humidity for a selected time period;
- removing said tape from said environment and allowing it to cool down in the presence of ambient temperature and relative humidity;
- and then copying the data on said tape onto new media.
