The Sony and Panasonic companies concluded the cooperation agreement in area of development of an optical disk of the new generation intended for long-term storage of information. Sony and Panasonic will combine the efforts and technological practices belonging to them for joint achievement of a common goal — development and start in production of an optical disk with a capacity at least 300 Gb intended for professional use. The companies while continue negotiations on specifications and parameters of future format of data recording. Sony and Panasonic intend to finish development of a disk of a new format with a capacity of 300 Gb by the end of 2015. According to representatives of the companies, the main destination of the carriers possessing such qualities, as moisture and frost resistance, ability to maintain differences of temperatures — to be a basis for creation of long-term storages of information.
Besides, an optical disk have to be capable to provide compatibility of formats of various generations, even on condition of their development over time that will make them suitable for preservation of information archives for many decades. Sony already submitted the decision for creation of archives of large volume on the basis of technology of an optical recording of information in September, 2012. Twelve optical disks, with a capacity of 25 Gb each, were collected in one compact cartridge. On the basis of these devices it is possible to create storages from 300 Gb in size to 1,5 Tb. Panasonic presented optical devices of data storage of the LB-DM9 series in July, 2013. The device only 20,8 millimeter thick contained in itself 12 disks with a capacity of 100 Gb. To 90 such compact optical storages it is possible to unite in information base up to 180 of Tb. Panasonic also used RAID technologies for ensuring speed of data transmission to 215 Mb/sec. in similar massifs.
