US Patent:
52454851, Sep 14, 1993
Filed:
Aug 30, 1991
Appl. No.:
7/753242
Inventors:
Edwin C. Dunn - Tucson AZ
Orvid B. Jeppson - Tucson AZ
Steven B. Wilson - Tucson AZ
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 1543
US Classification:
360 69
Abstract:
The invention is one or more tape systems which determine the length of tapes mounted therein to assess the thickness of such tapes. A format identifier is written at one of a plurality of locations on the tape depending upon the tape thickness. The format identifier for a relatively thin tape is written further from the leader block than that for a relatively thick tape, thereby avoiding the writing of user data in a region of the tape embossed with wrap deformations. The thickness determination is combined with a determination of the tape format to assess the compatibility of a desired operation on a tape mounted in a tape system therewith. If the operation is not compatible with the tape and the tape system, the tape system will not permit such operation to continue. A method for operating the tape systems is also disclosed, and accounts for various contingencies, such as blank tapes and marginal determinations of tape thickness.
