The invention relates to microelectronics and can be used to create storage devices on a cylindrical magnetic domains (CMD).

Famous replicate generator CMD containing magnitudinous film, which are osnovnosolskih magnetic domains and the conductive loop bus for embryonic cleavage domain and output split domain [1].

The disadvantage of this generator is the low reliability due to the loss of germ domain. The disappearance of the germinal domain leads generator completely inoperable. Typically, the disappearance of the germinal domain caused by the passage of random pulses of current through a conductive bus of the generator, for example, when it is turned on and off. At this embryonic domain is not replicated, and entirely removed from the main magnetic applications. The probability of failure is 10-6. In addition, the lack of generator is the complexity of managing the world, due to the fact that the recovery of germ domain, you must create an additional electronic device, providing conductive loop current pulse of the opposite polarity to restore embryonic domain that, in turn, necessitates the use of additional power supply.

Famous replicate generator containing magnitudinous film, on which are located the main magnetic applique to keep germ-domain soft-magnetic applications for output of the CMD and the conductive petrosaudi generator, connected electrically with the main and promotion channel CMD and for the restoration of embryonic domain under the main magnetic applique [2].

The disadvantages of this generator are insufficient reliability, due to the strong dependence of the current of the bubble nucleation temperature, and therefore the recovery of embryonic domain, for example, during operation of the generator at low temperatures may not occur, the probability of failure is with 10-6; the complexity of managing the world, due to the need to change the parameters of the control pulses when the temperature of the environment.

The aim of the invention is to increase the reliability of replicate generator and simplify the management world.

The objective is achieved by replicating the generator containing magnitudinous film, on which are located the main magnetic applique to keep germ-domain soft-magnetic applications for output of the CMD, and the conductive loop bus for embryonic cleavage domain and output split domain contains at least one additional magnetic aiz sides of each application and the minimum gap between them lie along the same vertical plane.

In Fig.1 presents replicate generator, General view; Fig.2 and 3, the same generator, vertical incision.

Replicate the generator contains magnitotron film 1, on which are located the main magnetic applique 2 to hold the germ of domain 3, the soft magnetic applications 4 for output of the CMD, the conductive loop-shaped bus 5 for splitting embryonic domain 3 and the conclusion derived domain, additional soft magnetic application 6 to hold the embryonic domain 7 located in the same row with the core 2, with a gap in the projection plane magnitogorskoi film, and one of the sides 8 of each application and the minimum gap between them lie along the vertical plane.

To replicate the generator along with the first additional applique 6 to hold the embryonic domain may include a second additional magnetic applique 9 located at a different level relative to the surface magnitogorskoi film and congruent with the first additional 6 in the projection plane magnitogorskoi film (Fig.3).

The essence of the invention lies in the fact that lost embryonic domain under the main application Vosstania embryonic domain under additional soft magnetic applique. The reliability of storage embryonic domain under additional applique almost absolute, because the supplemental application is free from the effect of any random current pulses. The replication process (in contrast to the nucleation process) consistently occurs in a wide temperature range, and it does not require any special electronic devices for recovery embryonic domain under the main application, and therefore much easier to control the world.

Storage reliability embryonic domain and range of passive replication can be increased by the approach of additional applications 6 to the surface magnitogorskoi film. This increases as the depth of the magnetic trap in which is stored a spare embryo domain, and the height of the barrier, producing passive replication of the domain in case of loss of primary embryonic domain. Additional soft magnetic applique can be made in two (or more) layers. For example, in the standard process one additional applique is formed in the same layer that the second film, is formed in the same layer with the main magnetic applique (Fig.3).

The location of additional applications in the same row with the core so that one of the sides of each application and the minimum gap between them lie along the same vertical plane, is selected as the effective stretching of the domain between applications. If the width of the gap exceeds 2 d, where d is the diameter of the bubble, the upper border of the process of stretching a spare embryo domain field offset in small fields of management is reduced below the upper limit of the operational capability of replicating generator, resulting in lower reliability.

The generator works as follows.

Embryonic domains 3 and 7 at the primary and secondary applications 2 and 6 respectively rotate independently from each other in the control magnetic field. The main magnetic applique 2 current loop 5 works as a normal replicate the generator. In the random pulse (or occasional lack of replicate pulse) current passing through the current loop, embryonic domain 3 under the main magnetic applique disappears. Then embryonic domain 7 on staticheskoi trap, located along the total for the two parties appliqués straight. During subsequent rotation of the control field on the 90oon the side of additional applications 6 facing the main applications 2, is formed magnetostatic barrier, cutting the stretched domain into two, each located under one application. In subsequent periods, rotation of the control field strain domains in the total magnetostatic trap does not occur because of their mutual repulsion. Due to the large masses of the two applications process passive replication steadily in the broader region in the coordinates of the NSIMP., MNC, completely overlap the area of health replicate normal generator. The probability of failure is no more than 10-12.

The proposed design of the generator can function without pulse replication. In this case, the primary germ domain displays the impulse transfer in the input channel as a whole, and then regenerated under the main magnetic applique described above. This simplifies the management world in the absence of the need to replicate the impulse.

Using the proposed replace recovery embryonic domain during one period of rotation of the control field, the probability of failure is no more than 10-12and does not exceed the probability of information failures; simplified management world due to the automatic recovery replicate generator without the use of special electronic devices or changes in external conditions.

REPLICATE the GENERATOR of the CYLINDRICAL MAGNETIC DOMAINS containing film magnitofononnogo material located on it appliqués magnetic material to hold the first germ of the domain to output a cylindrical magnetic domains and loop applique conductive material for splitting the first embryonic domain and output split domain, characterized in that it contains the application magnetic material for passive replication of the second embryonic domain, located in the same row with applique soft magnetic material to hold the first germ of the domain, while their side, along which the tension of the second embryonic domain for passive replication, are located on one straight line, and the adjacent sides of each application are located with a gap perpendicular to the sides, along which
