TDK introduces new heads of its own to HAMR-based hard disks, which will significantly increase the storage capabilities we know today
The new heads unveiled by TDK at the annual Sitek exhibition support the technology "HAMR", Or Head-Assisted Magnetic Recording. HAMR technology allows the hard disk to write information about stable magnetic materials using prior heating of the material, which is done with Laser. The heads the company has introduced will allow more compressed storage of information, which means that 15 gigabyte hard drives will be available next year.
The current technology of hard disks is limited by the media space of the hard disk on which a single bit of information is held. Hard disks with HAMR technology write the information on stable metal media (an alloy of platinum-iron) and use a laser to heat the material first, thus reducing the area where information can be written, without impairing the ability to read, write, and trust the disk.
According to a TDK spokesman, the first commercial hard disks to come with heads that support the HAMR technology are expected to appear at the end of 2015 and the beginning of 2016.
