Last week, Japan hosted a conference NAS EXPO 2016. This is the second in the history of this collection event. Around itself it gathers developers and manufacturers of storage in networked storage and creators of lost data recovery systems. The spectrum of visitors and participants' interest begins to flash drives and smart phones and ends clouds. It is reported that since the last time the number of participants and the visitors noticeably increased to 13 companies and over 10 000 visitors.
Our focus in this case raises forecast for the development of magnetic media. The data flow , is growing exponentially. For the most part this information trash. But for many it is expensive as memory and therefore priceless. storage systems Need for capacious hard drives will force the introduction of new technologies to improve recording density.
Today, the capacity of the magnetic plate 3.5 inch in diameter close to 2TB. By 2020, experts believe, wafer capacity for HDD 3,5-inch form factor will be doubled, which will produce 30-terabyte hard drives in seven plates with helium environment (at the conference was the report of the company Western Digital). However, conventional methods can not be perpendicular recording to achieve a recording density.
Record 4TB 3.5-inch "pancake" and 2TB 2.5-inch can turn with the introduction of so-called "island" recording (BPM, bit pattern media). To record BPM magnetic plates advance at the factory during manufacture etched so that the entire surface of the plate was coated magnetic dot plots.
Recording is performed by magnetizing each such point. The spatial sparseness points or islands of the magnetization and magnetic insulation does not allow adjacent points affect each other, which does not lead to data loss (demagnetization). Thus, the highest recording density is achieved. Related Products :
