SLIDER FOR HIGH-DENSITY MAGNETIC RECORDING PURPOSE, ESPECIALLY FOR PROVIDING THE SHAPE AND SIZE OF A HEAD GIMBAL ASSEMBLY SLIDER

摘要

PURPOSE: A slider for high-density magnetic recording purpose is provided to realize an ABS(Air Bearing Surface) in 2-layered U-shaped rail shape on a leading edge, and to expand a 2-layered main compression pad extended over by 2 external compression pads from a trailing edge of the ABS, thereby implementing an improved slider design. CONSTITUTION: A U-shaped rail(440) is expanded from a leading edge of a slider on an ABS(430). The U-shaped rail(440) is in 2-layered structure with the first surface(442) and the second surface(444) having a different level from the first surface(442). A main compression pad(450) is in 2-layered structure with the first surface(452) and the second surface(454) having a different level from the first surface(452). Two external compression pads(460) are extended over the main compression pad(450), and are located at the same level as the second surface(454) of the main compression pad(450).
