Toshiba is using HAMR and MAMR to create bigger drives
Toshiba has announced plans to bring 30TB+ hard drives to the commercial market in 2025.
The large capacities have been made possible through two magnetic recording technologies: Heat Assisted Magnetic Recording (HAMR) and Microwave Assisted Magnetic Recording (MAMR).
HAMR technology significantly enhances writing capabilities by heating the disk material with a near-field laser. HAMR does have its critics, with questions regarding the technology’s readiness, quality, reliability and compatibility, but all of the major drive manufactures are adopting it, and Seagate recently announced the results of an experimental test in which one of its Mozaic 3+ HAMR-equipped drives ran continuously, and problem free, for over 6,000 hours.
