HEAD SLIDER, DISC DEVICE AND CUTTING METHOD OF STICK-SHAPED WAFER

Japanese Patent JP3765907

B2

PROBLEM TO BE SOLVED: To suppress flying height fluctuation caused by a rail surface flatness tolerance produced at the time of slider machining and suppress flying height fluctuation caused by a machining tolerance of a taper length and obtain excellent flying characteristics by a method wherein a slider having an air flow-in end and an air flow-out end is so formed as to have a trapezoidal shape whose air flow-in end side is narrow and whose air flow-out end side is wide.
SOLUTION: A magnetic head slider 50A has an air flow-in end 52a and an air flow-out end 52b and has a trapezoidal shape whose air flow-in end side is narrow and whose air flow-out end side is wide. A pair of rails 54 and 56 which have flat rail surfaces 54a and 56a respectively are formed on the disc facing surface of the slider 50A. Tapered surfaces 54b and 56b are formed on the air flow-in side ends of the respective rails 54 and 56. As the rails 54 and 56 are so arranged as to come closer to each other on the air flow-in end side, a slit 58 is defined therebetween. A positive pressure is produced between the rail surfaces 54a and 56a and the air compressed once in the slit 58 part is expanded in a groove 60 part to produce a negative pressure.
