The descriptive initiative of manufacturers will almost certainly focus on what is known as MAMR, because there are certain advantages over HAMR. But to understand why most of these manufacturers include WD, Seagate or Toshiba, they will choose it, it is necessary to understand its fundamentals, which are well-monitored in specific areas.
The future is bright, MAMR will compete with HAMR for leadership
MAMR is a dictionary of Microwave-assisted Magnetic recording or translated into our language, microwave-assisted microwave recording, and has gained a lot of popularity due to the way it records data on desks: wave-based.
To do this, using high-speed magnetic fields using a magnetic recording process while the recording process takes place, which temporarily reduces the relative strength of the recording area, using what is known as a medium-sized object.
These microwaves reach the variable frequency of the microwave band itself, so the use of a microwave magnetic field oscillation layer is required for what is known as a torque oscillator or STO (Spin-Torque-Oscilator)
What we are trying to do is rotate the magnetic field at high speed with the STO, which is at the head of the generator to produce waves in the wide range 20 GHz to 40 GHz. To this end, the auxiliary capabilities are introduced in the current recording process resulting in more accurate recording and less energy in the writing process.
Smaller and more accurate writing heads
If as a result we are able to write more accurately and with less power, the next step we must take is to reduce the size of the writing heads, while at the same time an additional advantage: a greater increase in power.
This capacity should be allowed by the plates, which would have to modify their structures and materials to allow the highest accuracy of the heads. And that the heads should have at least two layers of magnetic field, because as the current passes through the first one, it causes the particles to break apart.
The second electromagnetic layer achieves a magnetic affinity, so that the incoming electrons in the electromagnetic wave have an effect on those within the plate's magnetism, which is able to modify its magnetic field slightly.
Since the frequency generated is similar to the material similarities that cover the plate, it is reached in the text in the visible areas to facilitate the conversion. Logically, the more STO is accessible, the more likely it will influence the smaller points of the plate object and the higher density will be achieved.
Therefore, all MAMR benefits will be based directly on improvements in STOs and chains, which are already generated in Damascus.
