Abstract
A magnetic head comprises a gapped media-contact surface formed by a pair of cooperating sections having corresponding planar surfaces abutted to each other. The planar surface of at least one of the sections has at least one narrow elongated slot containing a solidifiable bonding fluid, preferably epoxy, drawn therein under capillary attraction, the fluid upon solidifying bonding the cooperating sections together.

A gapped magnetic head comprising a first head section and a second head section abutted against each other at a common interface, said magnetic head further comprising:
- (a) two non-magnetic substrates in each of said sections;
- and
- (b) magnetic cores sandwiched between each pair of said non-magnetic substrates, wherein said first head section includes at least one narrow elongated slot extending therethrough, positioned on one side but not in contact with said magnetic core and parallel to and contiguous with said common interface, for receiving a solidifiable bonding fluid drawn therein under capillary action, the fluid, upon solidifying, forming a column of solid bonding material which bonds said head sections together.
A gapped magnetic head having a magnetic transducing gap, said head comprising:
- (a) a first head section comprised of a magnetic core sandwiched between a pair of non-magnetic substrates;
- (b) a second head section comprised of a magnetic core sandwiched between a pair of non-magnetic substrates and abuttingly engaging said first head section wherein a common interface is established therebetween;
- and
- (c) each non-magnetic substrate of at least one of said head sections having a relatively narrow elongated column of solid bonding material which is not in contact with said magnetic core, said column being contiguous to said common interface and parallel with aid sandwiched core, said column being fabricated by filling a relatively narrow elongated slot in each non-magnetic substrate of said head section with bonding material introduced therein via capillary action.
A gapped magnetic head comprising a first said section and a second head section abutted against each other at a common interface, said magnetic head further comprising:
- (a) two non-magnetic substrates in each of said sections;
- and
- (b) magnetic cores sandwiched between each pair of said non-magnetic substrates, wherein said first head section includes at least one elongated column of solid bonding material extending through said first head section positioned on one side but not in contact with said magnetic core and parallel to and contiguous with said common interface, formed from a solidifiable bonding fluid drawn under capillary action into at least one narrow elongated slot included in aid first head section, the fluid upon solidifying bonding said head sections to each other.
