Slider for magnetic head
Abstract
Abstract PURPOSE:To obtain a magnetic head slider to be used for both positive and negative pressure and having high floating property and rising at a low speed by forming grooves 25 passing air flow into cross rails. CONSTITUTION:The grooves 25 are formed on the cross rails 24 along the B direction coincident to air flow with a prescribed interval. A position recessed from the surface of side rails 22 between the side rails 22 is a negative pressure generating area 26. The depth l1 of the grooves 25 formed on the cross rails 24 is made coincide with the size l2 between the surface of the side rails 22 and the surface of the negative pressure generating area 26. When the magnetic head having said slider 21 is set up on a magnetic disc and the magnetic disc starts to rotate, the air flow is discharged through the grooves 25 of the side rails 24 and entered into the negative pressure generating area 26. Consequently, excessive negative pressure is prevented at the time of low speed rotation and low floating and the magnetic head is floated speedily from the surface of the magnetic disc.
