Floating type magnetic head

Claim 1

In a floating type magnetic head, for recording on and reproducing from a magnetic recording medium, comprising a pair of side portions each having a floating surface at one level facing the recording medium and adapted to float a small distance from the recording medium, a slider groove formed between said side portions defined by a bottom surface recessed below the level of said floating surfaces and a pair of tapered surfaces each bordering a respective one of said side portions and extending from said bottom surface of said slider groove to the floating surface of the respective one of said side portions, a core inserting groove extending through one of said side portions to the floating surface of said one side portion, and a magnetic core member disposed in said core inserting groove having an end portion extending to the level of said floating surface of said one side portion, said magnetic core member being fixedly mounted in said core inserting groove by a glass bonding agent applied around said core end portion in said core inserting groove, the improvement wherein said slider groove is formed with a portion of the tapered surface bordering said one side portion cut away below the level of said floating surface forming a recess in the tapered surface of said one side portion, said core inserting groove is located in said one side portion such that a part of said core when inserted in the core inserting groove proximate said core end portion has a common boundary with said recess in said tapered surface, and the glass bonding agent for fixedly mounting said magnetic core member in said core inserting groove is filled only in the recess in a space defined between said common boundary and said tapered surface such that no significant amount of the glass bonding agent is exposed at the level of said floating surface facing toward the recording medium.
