In August, 27, was held a conference IEEE TMRC Conference, devoted to the problems of magnetic recording, in particular, technologies that will increase the capacity of hard drives.
Solid state drives have already caught up with hard drives by volume, and even surpassed them, but will continue to give in terms of storage cost. As a result, consumers are, as before, consider hard drives as a means of storing large amounts of information.
Seagate Experts told the conference about the transition from the perpendicular magnetic recording technology, which provides a recording density of 1.3 Tbit / sq. inch, to technology tiled entries and a two-dimensional magnetic recording that will get index of about 1.5 Tbit / sq. inch.
To further increase the density may require the introduction of magnetic recording technology with the help of heating (heat-assisted magnetic recording, HAMR). This technology has been around for ten years, but in serial products have not yet been introduced. Hard Drive prototype with HAMR from WD was ready in 2013.
It is assumed that a conventional carrier HAMR will be available to the density of 4 Tbit / sq. inch, and on the support with discrete domains – 10 Tbit / sq. inch or more.
Appearance of the first HAMR hard drives on the market is expected as early as next year.
