In any case, the purpose of any hard drive manufacturer is based on three factors: high capacity, high speed and high safety. Of these can be added a living room can be attached to them or at least not to all, as it is a low cost of production.
SMR: a technology that has found population growth in this area
SMR technology was not the only manufacturers working at that time to achieve greater volume on their HDDs, so, usually when talking about SMR we often talk about PMR at the same time, because they are modern.
In any case, SMR dictionary of Magnetic Joint Recordings and it is a technology that has agreed to increase the number of bits of information that can be registered in a certain size disk. Obviously, the complexity of a lot of data can be stored in the field, the bigger the HDD capacity.
SMR is almost an extension of PMR, because they do not understand one without the other. PMR found something very important: reducing the physical limit of the HDD headset when writing or reading. This has been achieved write multiple pieces in the same space, which was free of the hard drive industry, but it wasn't enough.
SMR technology goes the distance and has gained something so far that can be determined: allow the magnetic track to exceed a portion of the pre-recorded material to increase the surface area. What is being reached is the possibility that the head of reading may have access to the written information of the uncovered portion of the magnetic tracks.
The lower space used for writing is equal to the final height of the height
To understand the evolution of this process, it should be noted that in the HDD without it, the magnetic tracks are compared in parallel to each other and (by reference only), that is, close to each other. .
On the other hand, with SMR the tracks can be changed more from each other because the reading head only needs less space than the written magnetic track. This only applies when the data to be written is new and is not edited or rewritten.
Why it's easy, avoid damaging nearby tracks. To do this, the edited data is written to an empty space of the disc, while the original track remains unchanged for a while. Not to fill HDD and duplicate or modified data, when completely inactive, the restructuring methods will work, we remove the original private track data and through it will be available to include additional data.
