Tape head having a support plate with contoured surface
View Patent ↗A tape recording head is provided comprising a support plate having a contoured surface with an opening in the contoured surface which allows head chips to protrude far enough to allow proper head tape contact for recording. The support plate is fixed on a coarse actuator so that the support plate and coarse actuator move together perpendicular to the motion of the recording tape. The head chips comprising rowbar substrates containing a multiplicity of recording elements are supported on a carrier mounted on a fine actuator and are not fixed to the support plate to allow low mass fine actuation.
1. A magnetic recording head, comprising:
a support plate having a contoured surface with an opening in said contoured surface;
at least one head chip comprising a substrate containing a plurality of magnetic recording elements, said head chip positioned to protrude through the opening in the contoured surface of the support plate for read/write access to a magnetic recording tape,
wherein the at least one head chip includes two transducing surfaces separated in a direction parallel to a direction of tape travel over the at least one head chip by a gap and held in fixed relation to one another,
wherein the head chip is moveable relative to the support plate in a direction perpendicular to the direction of tape motion over the contoured surface.
2. The magnetic recording head recited in claim 1 , wherein the contoured surface of the support plate is contoured in the direction of tape motion over the surface.
3. The magnetic recording head recited in claim 2 , wherein the contoured surface of the support plate is a cylindrical contour.
4. The magnetic recording head recited in claim 1 , wherein the opening in the contoured surface is approximately centered in said support plate.
5. The magnetic recording head recited in claim 1 , wherein the contoured surface of the support plate has a substantially rectangular shape.
