Toshiba Electronic Devices & Storage Corporation (Toshiba) has successfully achieved storage capacities of over 30 TB with two next-generation large capacity recording technologies for hard disk drives (HDDs): Heat Assisted Magnetic Recording (HAMR) and Microwave Assisted Magnetic Recording (MAMR). The demonstration drives represent a major milestone in the advance toward commercial products based on each of these emerging recording formats.

HAMR, one of the two technologies that are driving forward next-generation high-capacity data recording, boosts magnetic recording capabilities by locally heating the disk with near-field light. Toshiba achieved 32 TB on 10 disks and adoption of Shingled Magnetic Recording (SMR) technology. Toshiba plans to start shipping test sample HDDs with HAMR technology in 2025.
