Abstract
An improved composite magnetic recording head having a core chip with two opposed magnetic members via a magnetic gap and a nonmagnetic layer is disposed on at least one of the magnetic members and a thin magnetic layer is disposed on the non-magnetic layer. The thin magnetic layer has a higher saturation flux density than the magnetic members and the non-magnetic layer increases the adhesive strength between the thin magnetic layer and the magnetic member. The core chip fits into a slide member and is integrated using an adhesive glass.
