Latest Patents

One of his latest patents focuses on the air bearing surface of a head slider in a hard disk drive. This invention discloses a head slider designed to support a head over a magnetic disk, along with a method for manufacturing the head slider. The air bearing surface (ABS) features a relatively deep recess positioned in front of a trailing pad and an island pad. This design includes a recess formed between the trailing pad and the island pad of the ABS. In operation, this recess can reduce the peak pressure of the ABS, leading to a diminished mid-disk (MD) hump without compromising other performance parameters. Additionally, the reduction in peak pressure may also minimize lubrication pick-up from the magnetic disk.

Another notable patent by Bolasna describes an air bearing with low crown sensitivity through side channels. This air bearing surface of a slider achieves low crown sensitivity by incorporating a center channel and multiple side channels. At least one of the side channels is open to the center channel, allowing air to flow along the center channel toward the trailing edge of the ABS, thereby ensuring low crown sensitivity.
