Appeal No. 96-1890
Application No. 08/111,176
5 and 12 through 17 have been withdrawn as directed to a
nonelected invention.
The invention pertains to a method of identifying
magnetic tape characteristics. More particularly, the
invention employs patterns of magnetically polarized stripes
on the tape. As the tape is driven past a read/write head,
the head reads the pattern on the tape and decodes the
information in the pattern. The tape drive then responds
appropriately to the information in the reading/writing of
data on the tape.
Representative independent claim 1 is reproduced as
follows:
1. A method of providing information about
characteristics of a length of magnetic tape to a magnetic
tape drive having an arcuate scanning read/write head for
reading/writing on arcuate data tracks which are substantially
perpendicular to the length of the tape, comprising the steps
of:
providing a length of magnetic tape in a magnetic
recording drive, wherein the tape includes a pattern
containing encoded information, wherein the pattern is
positioned on at least one portion of the tape, the pattern
comprising a plurality of magnetically polarized stripes
parallel to the length of the tape and transversely spaced
from each other across the width of the tape, wherein the
stripes have a uniform and continuous direction of magnetic
polarization in the plane of the tape and substantially
perpendicular to the length of the tape, and wherein the
pattern is long enough to provide for the arcuate scanning
