Description

The invention relates to computer technology and can be used to build discrete information storage devices.

The purpose of the invention is to increase the fault tolerance of the drive for the storage device. '

The drawing shows a schematic diagram of the proposed drive.

The storage device for the storage device contains a layer 1 of magnetically uniaxial material with cylindrical magnetic domains (DEM) 2, on the surface of which there are information storage registers 3, interconnected through the main information input register 4 with the main DTM generator 5 and through additional information input registers 6 with additional generators 7 CMD. The information storage registers 3 are also connected through the DTM switch-replicators 8 to the main 9 and additional 10 information output registers, which are connected to the CMD reading element 11, Information input registers 4 and 6 are magnetically connected to the corresponding CMD annihilators 12.

The proposed drive operates as follows.

When recording, control signals in the form of a current pulse are supplied to the terminals of the main 5 and additional 7 CMD generators in accordance with the value of the bits of the recorded data word. The data word is entered in the main 4 and additional 6 input registers. At the same time, current pulses are sent to the conductive bus of the annihilators 12 of the CMD, which destroy (k-1) bits of the data word in each 1 ~ m input register 6 (0 <i £ k). When discharge a ₀ arrives at the (k-1) -th additional input register 6, current pulses are not supplied to the annihilator busbar and data word from the main 4 and additional 6 information input registers are entered into information storage registers 3 in parallel.

When reading information, the data word, moving through the information storage registers 3, enters the 8 CMD switches-replicators 8 and is translated by a current pulse of negative polarity sprinkled into the conductive bus of the switches — rep 1275538 2 CMD 8 liquors from the information storage registers into the main 9 and additional 10 output registers CMD, The discharges of a read block sequentially arrive at the CMD reading element 11 due to the fact that the capacity of each i-th additional register 10 of the output of the CMD is greater than the capacity of the main register RA 7vyvo10 and TsMD on (k-i) categories.

The invention relates to computing and can be used to construct devices for storing discrete information. The purpose of the invention is to increase the fault tolerance of the storage device for the storage device. The drawing shows the principle on the scheme of the proposed drive. The drive for the storage device contains a layer 1 of a magnetically one-axis material with cylindrical magnetic domains (CMD) 2, on the surface of which are located the information storage registers 3 interconnected through the main information input register 4 with the main information generator 5 and with additional 7 CMD generators. The information storage registers 3 are also connected via replicators 8 CMD switches with the main 9 and additional 10 information output registers, which are connected to the CMD reading element 11, Information input registers 4 and 6 are connected to the corresponding CMD annihilators. The proposed drive works as follows. When recording, the control signals in the form of a current pulse arrive at the outputs of the main 5 and additional 7 CMD generators in accordance with the value of the bits of the data layer to be written. The data layer is entered into the main 4 and additional 6 registers of the VEUID. In this case, current pulses are applied to the current-carrying bus of the CMD annihilators 12 CMD, which destroy (k-1) bits of the data word in each i-th input register 6 (). When a bit a (k-1) -and additional register 6 is entered, current pulses are not fed into the conductor bus of the annihilator, and a word word is entered from the main 4 and additional 6 data-input registers into the storage registers 3. information. When reading information, the data word, promoted through the information storage registers 3, enters the CMD replicators 8 and is converted by a negative polarity current pulsed into the current bus of the replica switches 82 of the modulators In the CMD from the information storage registers to the main 9 and additional 10 CMD output registers. The bits of the read block are successively entered into the CMD read element 11 due to the fact that the width of each i-ro additional register 10 of the CMD output is greater than the width of the main register of the CVP on (k-i) bits.
