Disk Protrusion Measurement in a Back-Heating Study for Heat Assisted Magnetic Recording

Shaomin Xiong, Robert Smith, Erhard Schreck
Proc. ASME. ISPS2020, ASME 2020 29th Conference on Information Storage and Processing Systems, V001T05A004, June 24–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: ISPS2020-1950
https://doi.org/10.1115/ISPS2020-1950
... Abstract Heat assisted magnetic recording (HAMR) is a promising technology for the next generation hard disk drives (HDDs). Understanding the heat transfer at nanoscales and implementing a proper thermal management scheme become very critical as a few heat sources and energy delivery components...
