Latest Patents

Kok Hoe Chia's latest patents include groundbreaking advancements. The first is a **Disc Drive Power-Up Process Including Head Mapping**, which involves constructing a logical-to-physical head map during each power-up of a disc drive. This process ensures that after powering the controller and spindle motor, a bias current is iteratively supplied to the read heads. The stored voltage across each read head is compared to a threshold, determining its fault status. This logical-to-physical mapping plays a crucial role in optimizing the controller's memory based on the operational status of the heads.

His second patent, **Proposal of Capacity Tuning in the Production Process of Storage Disc Drives**, aims to automatically configure disc drives to their ideal capacity based on the data transfer capabilities of head/disc surface combinations. This innovation assesses the error rates of these combinations and selects among three drive configuration schemes. It introduces a variable bits per inch (BPI) scheme, optimizing data rates between weak and strong combinations, as well as addressing issues through head depopulation and de-frequency schemes.
