Appeal No. 95-0884
Application 07/805,098
was filed concurrently with the appeal brief and was entered by
the examiner. This amendment cancelled claims 11-14.
Accordingly, this appeal is directed to claims 1-10, which
constitute all the claims remaining in the application.
The claimed invention pertains to an apparatus for
positioning the head of a tape drive relative to a tape. More
particularly, the head is carried on a carriage which has thread
means thereon. A lead screw engages the threads on the carriage
to move the head when the lead screw is rotated. The threads of
the lead screw are held in firm camming frictional engagement
with the carriage thread means by a spring means.
Representative claim 1 is reproduced as follows:
1. A head positioning apparatus for a tape drive for
positioning the head of the tape drive relative to the tape and
including a carriage carrying the head and drive means, including
a lead screw, operative in response to rotation of the lead screw
to move the carriage and thereby position the head, characterized
in that the drive means includes thread means fixedly defined on
the carriage and spring means acting on the lead screw and urging
the lead screw laterally relative to the rotational axis of the
lead screw into firm camming frictional driving engagement with
the carriage thread means.
