The first hard drive with HAMR will be on the market next year

In August, held the 27 in a row, the conference IEEE TMRC Conference on the problems of magnetic recording, in particular, technologies that will increase the capacity of hard drives.

SSDs have caught up with hard disks in volume, and even surpassed them, but will continue to give in terms of storage cost. As a result, consumers as before considering hard drives as a means of storing large amounts of information.

Seagate also told the conference about the transition from technology perpendicular magnetic recording, providing a recording density of 1.3 Tbit/square inch, to technology, tile entry and two-dimensional magnetic recording, which will allow you to get a record of around 1.5 Tbit/square inch.

For a further increase in density may require the introduction of the technology of magnetic recording using heat-up (heat-assisted magnetic recording, HAMR). This technology is known for ten years, but the commercial product has not yet been implemented. A prototype hard drive with HAMR at WD was ready in 2013.

It is assumed that the conventional HAMR media will be to get the density up to 4 Tbit/sq. inch, and on the media with discrete domains — up to 10 Tbit/square inch or more. The introduction of the first HAMR hard drives in the market is expected next year.
