The problem of to casing of magnetic head R arc side edge.
A kind of head stack provided by the present application includes the head stack of shell and suit inside the shell, the magnetic head
Component includes a group or more of magnetic core group, clamper and clamp spring, and the magnetic core group is fixed in the slot of clamper formation,
Two clampers of opposite installation are clamped using clamp spring；The upper surface of the shell is R cambered surfaces, R cambered surfaces middle section
Thickness be more than the thickness of marginal portion, the R arc radius of outer surface is less than the R arc radius of inner surface, and the R arc side edge of outer surface
Less than the R arc side edge of inner surface.
Preferably, the upper surface of the shell is the R arcs of the 10mm radiuses of the polished formation of R cambered surfaces of 12mm radiuses
Face.
Preferably, the height of the shell is 3.8mm.
Present invention also provides it is a kind of include above-mentioned magnetic card magnetic head magnetic card reader.
Compared with prior art, the application has the following advantages：
The application preferred embodiment can effectively solve existing magnetic card magnetic head by the means for extending downwardly the edge of R arcs
The hidden danger of R arc side edge may be encountered when swiping the card；Simultaneously as shell upper surface and the thickness of magnetic card contact site compare both sides
Marginal portion thickness it is big, the durability of product can be increased, extend the service life of product.
