Many methods are proposed to solve those problems, such as Heat-Assisted Magnetic Recording (HARM), Bit-Patterned Media (BPM), Exchange-Coupled Composite media (ECC) and so on.

针对这一系列问题，人们提出了热辅助磁记录、构型记录位介质以及交换耦合复合介质等解决方案。

The conference included many papers on various aspects and issues in energy assisted magnetic recording (HAMR is one version of this) as well as a technology called shingled magnetic recording where magnetic recorded tracks are written offset from each other giving a higher track density and thus more storage capacity.

FORBES: Digital Storage, Our Only Hope

With the announcement of heat assisted magnetic (HAMR) recording products by 2014 a few weeks ago Seagate could produce thin (7 or even 5 mm thick) 5, 400 RPM hybrid HDDs with storage capacities of 1 TB within the next couple of years.
