Associates visited scientific research laboratory Of seagate and published completely interesting report about their past time there. Let us give the words of the technical director of company, Mark : "When I arrived to Seagate 8 years ago, space in 100 Gbit square seemed improbable, even 20 Gbit to the square were seen by improbable". Now Mark and its associates reached index in 421 Gbit/sq. in and this far from limit. By the limit of the technology of perpendicular record are now seen approximately 1 tbit/sq. in, after which Seagate is intended to master the new technologies, which will make possible to bring this index to 50- TI (!). in connection with hard disk of standard form factor 3,5 inches this designates the volume of the contained information into 30 Tb. About the technology, which will make possible to attain the impressive breakthrough, we already wrote. She is called HAMR (heat-assisted magnetic recording, magnetic recording with the aid of warming-up). In this case we are talking about magnetic disks with in the process of work with the aid of laser regions, to which at each given moment is produced the record. The data are written more easily, after which the zone of record is cooled to the thoroughly heated region and thus it is stabilized. This approach makes possible to overcome the theoretical limit of magneto-optical technology - the so-called super-paramagnetic limit, connected with the fact that with a increase in the capacitance of disks increases the speed writing of information, i.e., the number of magnetic particles by the unit surface area of disk. With the very high speed writing adjacent particles begin to act on each other, and recorded thus data are lost. Earlier about the works in the mastery HAMR was already reported Fujitsu and Hitachi. Commercial products for the base of this technology seagate expect to be released in the followings months.	HDD WITH 30TB CAPACITY
