channel 13, the second defect-storage registers 30 with switches 31 and 32 connected to the main part 10 of channel 9, the second additional logical elements 33, one inputs 34 of which are connected to outputs 29 of switches 27 and 28 and the other inputs 35 are connected to the second 30 storage registers of the defect map, two outputs 36 and 37 of each of the elements 33 are interconnected and connected to the inputs 34 of the adjacent elements 33, and the third outputs 38 are connected to the second registers 30 of the 15 defect map. The first registers 17 for storing the defect map with switches 18 and 19 are located between parts 10 and 11 of channel 9, and the second registers 30 of storing the defect map with switches 31 and 32 CVPs are located between part 10 and channel 13. The drive also contains a register 39 input search with generator 40. CMD records, elements 41 of the information array fencing.

The accumulator is based on the well-known method of controlling the advancement of the CMD by means of ferromagnetic applications and the magnetic field controlled rotating in the plane of a magnetically uniaxial film. The control magnetic field induces in elements 3 of the advancement of the high pressure cylinder 2 magnetic poles, which interact with the high pressure cylinder and provide the movement of the latter.

The drive works as follows.

Before switching on in operating modes, information is received on the defective registers (defect map), which is recorded in registers 17 and 30. The definition of defective registers is performed as follows.

From the generator 40, the control information sequence of the high-pressure cylinder for recording into registers 4 goes to register 39. After recording the information, elements 5 and 6 are sent to the registers 4 and then copied by elements 7 to channel 9 section 10. Advance through 10 through elements 20, the central spare parts get into the channel section with dual switches 26 and 27 on

Sensors 14 and 15, information on the vital registers goes to a control unit (not shown). The control device generates a pulse sequence for recording the CVP to the l2 generator, provides the recording of the CVD to the registers 4, advancing the CVP along the number of channel 11, copying the CVD to the clock 10 of channel 9, advancing part of the switches 31, switching the switchboard with switches 31 to registers 30. Then the defect map is recorded in registers 17 by operating the generator 12, moving the high-pressure cylinder through part 11, switching the high-pressure cylinder by means of switches 18 to registers 17. Registers 17 and 30 contain information about defective registers (card defects) is kept permanently If necessary, this information includes switches 19 of registers 17, switches 32 of registers 30 output of high-pressure cylinders, respectively, to part 11 of channel 9 and further to fencing 41, as well as to part 10 with switches 27 and further to fencing 41.

The read mode in the accumulator is implemented as follows.

The selected information word is copied with elements 7 in sections 8 into part 10 of channel 9. Discharges of this word fall on the inputs

21 elements 20. If the DVCs are copied into elements 20, containing inputs 21 and

22 and outputs 23–25, from the interaction in sections 8 with the CVP of defect-free registers 4, and in the corresponding registers 17 the CVPs were not recorded (no defects), i.e. nothing enters the inputs of the 22 elements 20, the elements 20 do not shift the bits of the information sequence of the high-pressure cylinder, and the information passes these elements unhindered. If the information is copied into elements 20 from interaction in places 8 with empty (holes) bits of defective registers, which indicates the absence of CVP in registers 4, then, starting with the next bits, all CVPs interact in elements 20 with CVP of registers 17 (CVDs are fed to inputs 22) and are shifted at the inputs

sensors 14 and 15, information about the defective registers enters the control unit (not shown). The control unit generates a sequence of pulses for recording the CVP to the l2 generator, records the CVP to the registers 4, advances the CVP through part of the channel 11, copies the CVP to part 10 of the channel 9, advances through part 10 to the switches 31, switches the switch with the help of switches 31 registers 30. Then the defect map is recorded in registers 17 due to the operation of generator 12, promotion of the high-pressure cylinder in section 11, switching of the high-pressure cylinder by means of switches 18 to registers 17. Registers 17 and 30 contain information about defective registers (defect map) cautiously. If necessary, this information includes switches 19 of registers 17, switches 32 of registers 30 output of HPC, respectively, to part 11 of channel 9 and further to fencing 41, as well as to part 10 with switches 27 and further to fencing 41.

The read mode in the accumulator is implemented as follows.

The selected info word is copied using elements 7 in sections 8 into part 10 of channel 9. Discharges of this word fall into the inputs

21 elements 20. If the DVCs are copied into elements 20, containing inputs 21 and

22 and outputs 23–25, from the interaction in sections 8 with the CVP of defect-free registers 4, and in the corresponding registers 17 the CVPs were not recorded (no defects), i.e. nothing enters the inputs of the 22 elements 20, the elements 20 do not shift the bits of the information sequence of the high-pressure cylinder, and the information passes these elements unhindered.

 23 and 24 elements 20 one or two bits ahead. At the same time, it performed the ettac as the distance between the bits of the sequence of a CSR is two to four periods, i.e. two times more compared with the period of shift 1SC. The passage through part 10, get to the inputs 28 of the dual switches 27, switch to the outputs 29 and, moving forward, fall into the channel 13 section with elements 33 containing inputs 34 and 35 and outputs 36-38. The interaction in elements 33 with TSCH of registers 30 (when information is supplied to inputs 35), the CVDs of channel 13 of the information sequence, similarly to the described partial compression, are adjusted (compressed) for another one or two periods of advance elements at outputs 36 and 37. After the full required compression of the sequences of the CV is performed D information is advanced further, enters expander 14, is read by sensors 15 and 16, and enters barrier 41 above.

The recording modes with pre-erasing information are provided by the operation of the generator 40, register 39, input elements 5 and output 6.

Thus, in operating modes, information is recorded, erased, and corrected (corrected), taking into account the false information of defective registers.
