Seagate regularly demonstrates its own progress in the development of magnetic recording technology heating, promising to start shipping samples of the appropriate type drives in 2017, or even at the end of next year.
The first prototypes of hard drives with technology HAMR because of layout features have increased the distance between the magnetic plates, and seriously increase the recording density can not be right. For this reason, the first prototypes of the hard drives in the volume will be limited to 4GB or slightly greater capacity. The heating portion of the magnetic plate before recording and all subsequent procedures shall be stowed in 20 ns, this limit the speed of the hard drive. A laser with a wavelength of 810 nm has a power of 20 microwatts, it is able to heat the portion of the magnetic plate to a temperature of 450 degrees Celsius in a short time.
Even in mass production drives HAMR technology will cost about 10% more than their predecessors. However, by 2025, improvements should allow hard drives to create a volume of 100 TB. HDD manufacturers are convinced that solid state drives will never replace hard disks, magnetic plates, since the latter will offer a better price data storage. Related Products :
