Title: Kirk Hwang: Innovator in Magnetic Data Storage Technologies

Introduction

Kirk Hwang is a prominent inventor based in Palo Alto, CA, known for his significant contributions to the field of magnetic data storage devices. With a total of 14 patents to his name, Hwang has developed innovative solutions that enhance data storage efficiency and reliability.

Latest Patents

Hwang's latest patents include groundbreaking technologies such as "Track-band squeezed-sector error correction in magnetic data storage devices." This invention describes data storage devices utilizing a two-level ECC scheme, which allows for the recovery of sectors in a squeezed group of tracks. The scheme incorporates both a single track level ECC and a track band ECC that functions across multiple tracks, using additional parity information calculated from input data to enable correction across tracks. Another notable patent is "Error correction with on-demand parity sectors in magnetic data storage devices." This invention addresses the squeeze-error problem that occurs when writing a second track causes errors in an adjacent previously written track. The ECC system generates additional on-demand ECC information to correct data errors without the need to rewrite the track.
