Appeal No.95-2807
Application 07/944,653
Appellant’s invention relates to a magnetic head for a tape
recording/reproducing apparatus. Appealed claim 1 recites that
the head comprises a “slidable surface” (which we interpret as
being a tape sliding surface inasmuch as this surface of the head
is not “slidable” in a literal sense) and first and second
magnetic gaps (1A, 2A). The first magnetic gap is recited to2
correspond to a first running direction of the magnetic tape, and
the second magnetic gap is recited to correspond to a second
running direction of the tape. According to claim 1, each of the
magnetic gaps lies between a head peak (9, 10) of the slidable
surface and a tape departure point (7, 8) downstream from the
head peak so that it is effectively offset from the peak.
A copy of the appealed claims, as these claims appear in the
appendix to appellant’s brief, is appended to this decision.
The following references are relied upon by the examiner in
support of his rejections under 35 U.S.C. § 102(b) and 35 U.S.C.
§ 103:
Takanohashi et al. (Takanohashi) 4,387,410 Jun. 07, 1983
Favrou et al. (Favrou) 4,875,129 Oct. 17, 1989
2Although the magnetic gaps are not specifically defined or
described in appellant’s specification, U.S. Patent No. 4,849,841
issued to Edmund Sokolik states that a magnetic gap in a tape
recording/reproducing head of an electromagnetic transducer core
structure lies between confronting pole faces of the core. This
patent was cited in the first office action in this application.
