Title: Sujit Kirpekar: Innovator in Hard Disk Drive Technology
Introduction
Sujit Kirpekar is a notable inventor based in Fremont, CA, who has made significant contributions to the field of hard disk drive technology. With a total of 2 patents, his work focuses on enhancing the performance and reliability of data storage devices.
Latest Patents
One of Kirpekar's latest patents is for a "Multiple-sense thermo-resistive sensor for contact detection of read-write heads." This invention involves detecting a touchdown between a read/write head of a disk drive and the surface of a magnetic disk using multiple sensors located at the air-bearing surface (ABS). The use of multiple sensors increases the likelihood of detecting a touchdown event, which occurs when a portion of the ABS contacts the underlying magnetic disk surface. The friction generated during this contact produces heat, altering the electrical resistance of at least one sensor. This change can be monitored to identify touchdown events effectively.
Another significant patent is related to "Fly-height management in a hard disk drive (HDD)." This invention includes a first resistive temperature detector (RTD) that detects temperature generated by the proximity of a slider to the media. Additionally, a second RTD is used to detect temperatures correlated to the fly-height of the slider. The integrated circuit (IC) in the HDD determines the fly-height based on the temperature readings from both RTDs, enhancing the overall performance of the hard disk drive.
