Toshiba's HAMR and MAMR mechanical hard drive technologies both exceeded the 30TB mark, with the latter achieving 11 platters for the first time in the industry

According to news from this site on May 15, Toshiba recently announced that it successfully demonstrated a 32TB HAMR mechanical hard drive and a 31TB MAMR mechanical hard drive.

Notes on this site:

HAMR is Heat Assisted Magnetic Recording, the full name is Heat Assisted Magnetic Recording, which enhances magnetic recording capabilities by locally heating the disk with near-field light;

And MAMR It means microwave-assisted magnetic recording, the full name is Microwave Assisted Magnetic Recording, which uses microwaves to enhance the magnetic recording capabilities of mechanical hard drives.

Toshiba’s 32TB HAMR mechanical hard drive adopts a 10-platter design and uses SMR shingled magnetic recording technology, which makes its storage density the same as Seagate’s Magic Color Box 3+ The HAMR platform is basically the same, and the latter's 10-disk SMR version also has a capacity of 32TB.

Toshiba expects to begin sampling its HAMR mechanical hard drive in 2025. Foreign media Blocks & Files reported in a report that the capacity of these sample products will be 28~30TB, not reaching 32TB, so it may be a traditional CMR magnetic recording version.

Toshiba confirms that its 31TB MAMR mechanical hard driveis the first in the industry to implement an 11-platter design, with SMR and improved signal processing technology to promote the storage of this mechanical hard drive The density reaches 2.8TB per platter. In the press release, Toshiba praised its long-term close cooperation with platter manufacturer Resonac Corporation (reorganized from the former Showa Denko SDK) and magnetic head manufacturer TDK.

The above is the detailed content of Toshiba's HAMR and MAMR mechanical hard drive technologies both exceeded the 30TB mark, with the latter achieving 11 platters for the first time in the industry. For more information, please follow other related articles on the PHP Chinese website!
