Claims
- 1. A floating magnetic head comprising:
- a substantially rectangular slider having a top surface and a bottom surface having a floating surface, the slider made of a non-magnetic material and having leading and trailing ends said slider having side surfaces located between the top and bottom surfaces extending from the leading end to the trailing end, the slider being provided with a groove in one of said side surfaces which gradually increases in depth along one side of the slider extending toward the trailing end and has an opening at the trailing end;
- rails mounted on the floating surface of the slider which is opposite to a magnetic recording medium to produce a floating force;
- a magnetic head core being bonded to said one of the side surfaces of the slider external to the rails with a glass film which is formed on said one of the side surfaces of the slider;
- the magnetic head core having first and second legs, the second leg being located at the trailing end of the slider without protruding from the trailing end such that the first leg is located between the second leg and the leading end of the slider, the magnetic head core having a read/write gap; and
- a first coil wound around the first leg in a first sense and a second coil wound around the second leg in a second sense opposite to the first sense, the first coil and second coil being connected in series, the first coil and the second coil being at least partially in the groove, wherein the length of the groove measured in the longitudinal direction of the slider is greater than the length of the magnetic head core measured in the longitudinal direction of the slider.
- 2. The floating magnetic head of claim 1, wherein the length of the magnetic head core along the longitudinal direction of the slider is more than one-tenth but no more than one-half of the length of the slider.
- 3. The floating magnetic head of claim 2, wherein the magnetic head core has an inclined face, the inclined face being close to a surface of one of the rails and opposite to the slider and magnetic head core bonding surface.
