FIELD: data processing.
SUBSTANCE: group of inventions relates to information processing. Device comprises a unit for making a decision on a recording system for generating basing on characteristics of data to be recorded on a recording medium multiple areas of recording on a logical device configured by the recording medium and making a decision on recording systems to be used in each of the recording areas; and a unit for initializing the logical device for initialization of each of the recording areas of the logical device basing on certain recording systems, herewith the characteristics of data recorded on the recording medium are characteristics including the value of storage duration, which is the period of storing data, and the value of error coefficient, which is a percentage of errors allowable for generating when reading data; and the recording systems additionally contain a recording system using a multilevel cell (MLC), in which the redundancy code is set so, that the possibility of correcting an error is low and the degree of redundancy of levelling the recording is set at a low value, and/or a recording system using a MLC, in which the redundancy code is set so, that no possibility of correcting an error is required and the degree of redundancy of levelling the recording is set at the medium level value.
EFFECT: technical result is optimizing a data recording system in accordance with the use.
