Abstract

A read/write magnetic transducer head is formed using a straight ferrite core piece. The window which accommodates the coil is formed in the slider. As shown in Fig. 1, a ferrite slider 3 has a suspension groove 4, air bearing surfaces 5 and a groove or window 6 formed in the trailing wall surface 7. A straight ferrite core piece 8 is secured to rear wall 7 by means including glass 9 to form a read/write gap 10 at the trailing portion of the central rail 11. Core piece 8 carries a surrounding coil 13 which is partially received in the window or groove 6.

Reverse Window Ferrite Head

A read/write magnetic transducer head is formed using a straight ferrite core piece. The window which accommodates the coil is formed in the slider. As shown in Fig. 1, a ferrite slider 3 has a suspension groove 4, air bearing surfaces 5 and a groove or window 6 formed in the trailing wall surface 7. A straight ferrite core piece 8 is secured to rear wall 7 by means including glass 9 to form a read/write gap 10 at the trailing portion of the central rail 11. Core piece 8 carries a surrounding coil 13 which is partially received in the window or groove 6. This structure has enabled a reduction in the effective path length of the magnetic circuit, locating the coil closer to the magnetic circuit, locating the coil closer to the recording gap, a reduction of backgap flux loss facilitated by extended area, and a reduction of flux loss at the apex area by use of a larger apex angle.
