Abstract
In a magnetic head having magnetic cores for performing recording and/or reproducing and erasing of information onto and/or from and from a magnetic recording medium and a slider for supporting the cores, a member for shielding the magnetic cores magnetically is provided in the slider. When accessing information by sandwiching a magnetic recording medium between the two opposing portions of a pair of the magnetic heads, crosstalk is reduced between the magnetic cores and thus recording and/or reproducing errors are prevented. The reliability of the magnetic head is improved.
Claims18
A pair of magnetic heads for use with a recording medium having first and second opposing surfaces, comprising
- first and second sliders each having a surface adapted for sliding on the first and second surfaces respectively of said recording medium, the surface of each of said sliders having first and second lands separated by a groove, the first and second lands of said first slider being opposite the second and first lands of said second slider, respectively;
- first and second magnetic cores embedded in the first lands respectively of each of said first and second sliders and being adapted to slide on the first and second surfaces of said recording medium, said first and second magnetic cores extending in a direction substantially perpendicular to the surfaces of said sliders and being spaced in a direction parallel to the surface of said sliders by a predetermined track displacement distance;
- and
- first and second magnetic shielding members embedded in said first and second sliders respectively, said first and second shielding members extending in a direction substantially parallel to said first and second magnetic cores, being positioned therebetween, and being substantially coextensive therewith whereby said shielding members magnetically shield said first and second magnetic cores from each other.
