FIELD: information technologies. ^ SUBSTANCE: invention is related to external memorising devices of electronic computing machines and may be used in other systems, where it is required to memorise digital or analog information on magnetic medium. Memorising module comprises information medium in the form of thin-walled hollow circular cylinders of various diametres, which are installed coaxially relative to common geometric axis, where thin-walled hollow circular cylinders of various diametres of the first and second group with their edges are rigidly connected to various sides of axisymmetric base, on internal and external surfaces of all thin-walled hollow circular cylinders of various diametres there are magnetic memorising layers applied, facilities for rotation of information medium comprise rotation shaft, which is rigidly connected to axisymmetric base of information medium, facilities for positioning of converters - elements of information registration and perception - comprise stepped motors tightly installed on external sides of memorising module bases, drive screws are installed on shafts of stepped motors, nuts are installed on drive screws, piezoelectric linear motors are installed on nuts, disk-carriers are installed on piezoelectric linear motors, levers with floating blocks of magnetic heads are installed on disk-carriers with the possibility of displacement of levers with floating blocks of magnetic heads together with disk-carriers in axial direction above magnetic memorising surfaces of information medium through radial slots in half-casings, levers with floating blocks of magnetic heads are installed at specified angles relative to each other, so that floating blocks of magnetic heads of nearest neighboring thin-walled hollow circular cylinders are distanced by angle, floating blocks of magnetic heads of each thin-walled hollow circular cylinder are installed on each lever with floating blocks of magnetic heads with shift relative to each other along parallel geometric axis of information medium. Pitch between magnetic heads in floating block of magnetic heads, mutual location of levers with floating blocks of magnetic heads and mutual location of floating blocks of magnetic heads provide for specified location of record paths on magnetic memorising surfaces. ^ EFFECT: increase of record transverse density, increase of record longitudinal density, higher information capacity. ^ 3 dwg |
