Title: Innovations of Sze Chek Tan in Shingled Magnetic Recording Technology
Introduction
Sze Chek Tan is a notable inventor based in Singapore, recognized for his contributions to the field of data storage technology. He holds a total of 4 patents that focus on enhancing the efficiency and capacity of shingled magnetic recording (SMR) systems. His work has significantly impacted the way data is stored and retrieved in modern storage devices.
Latest Patents
One of Sze Chek Tan's latest patents is titled "Shingled magnetic recording storage system with reduced time to recover." This technology introduces a method that minimizes recovery time in storage systems. The method involves entering an idle status, determining if there is an incomplete band update operation, and invalidating a media scratch pad (MSP) by clearing headers if no incomplete operation is detected. The process includes performing a power cycle, reading an MSP header, and validating it. If a rude power cycle occurs and the MSP header is valid, the MSP is examined and restored if necessary. Conversely, if a safe power cycle occurs, an MSP restore operation is not required, thus reducing recovery time.
Another significant patent is "Maximize SMR drive capacity," which describes systems and methods for optimizing the capacity of SMR drives. In this embodiment, the SMR drive includes a main store for user-accessible data, a media cache, and a media scratchpad for temporary internal data storage. The storage controller processes read and write requests, and the main store may consist of both shingled and unshingled media partitions. The storage controller designates certain data tracks from the shingled media partition as temporary data track guard bands, enhancing overall storage efficiency.
