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.
