Description

This invention relates to the field of magnetic recording. A device for magnetic recording and reproducing information comprising a magnetic heads assembly capable of providing movement of a magnetic tape at a nominal speed is known. A known device provides a magnetic recording of information on a movable magnetic tape or its reproduction. A disadvantage of the known devices is the impossibility of providing simultaneous magnetic recording and reproducing in ((Ormatia. Also known is a device for magnetic recording and reproducing information containing the first node of magnetic heads having the ability to move the magnetic tape at a nominal speed and mounted on one case with the second magnetic heads assembly 2. This device allows simultaneous magnetic recording and reproduction of information. Moving the magnetic tape at a nominal speed simultaneously through the first and second nodes of the magnetic heads, which leads to a significant dependence of the processes, magnetic recording and information reproduction by the first and second magnetic nodes, heads. The purpose of the invention is to reduce the dependence of magnetic recording and playback of information first. and the second nodes of magnetic heads. This is achieved by the fact that in the proposed device for magnetic recording and reproducing information a loop of magnetic cients, mounted on the housing between the first node and the second magnetic head assembly of magnetic heads having the opportunity to move a magnetic tape at a nominal speed with the speed and the forward and reverse .peremolki. In this case, the second node of magnetic heads has the possibility of pulling the magnetic tape out of the accumulator of the loops of the magnetic tape and introducing it into it. FIG. 1 shows the proposed magnetic recording device; and

reproduction of information; in fig. same device, embodiment.

The device contains the first node

1 magnetic heads / having the ability to move the magnetic tape 2 at a nominal speed adopted for the processes of magnetic recording and reproduction of information, the First node 1 of magnetic heads is mounted on one case with the second node 3 magnetic heads.

The device also contains an accumulator 4 loops 5 of magnetic tape 2 fixed on the case between the first node 1 of the magnetic heads and the second node 3 of the magnetic heads having the possibility of providing the movement of the magnetic tape

2 with nominal speed and forward and rewind speeds. In this case, the second node of magnetic heads has the possibility of pulling out magnetic tape 2 from accumulator 4 loops 5 and introducing it into ngo.

In the proposed device, in the process of magnetic recording and reproducing information, the first node 1 of the magnetic heads makes the introduction of the magnetic tape 2 into the drive 4 of loops 5 as it moves at nominal speed. The second node 3 of the magnetic heads, when moving the magitite tape 2 at a nominal speed, pulls it out of the accumulator 4 loops 5. In the process of direct rewinding of the magnetic tape the second node 3 of the magnetic heads pulls it out of the accumulator 4 loops 5, and in the process rewind - its introduction to it.

A variant of the proposed device shown in FIG. 2, is intended for magnetic recording and reproduction of photo-telegraphic signals. In this device, the first node 1 of the magnetic heads contains a block 6 of magnetic recording heads, a mechanism 7 for moving the magnetic tape 2 at a nominal speed, and a mechanism 8 for tensioning the magnetic tape 2. The second node 3 of the magnetic heads contains a block 9 of magnetic playback heads, a mechanism 10 for moving the backhaul tapes 2 with a nominal speed and a mechanism 11 for direct and rewind the magnetic tape 2. In addition, the block 6 of the magnetic recording heads and the block 9 of the magnetic heads of reproduction can be made in the form of synchronously rotated discs.

Block 6 of the magnetic recording heads provides magnetic recording of photo-telegraphic signals onto magnetic tape 2, which is moved relative to it at a nominal speed and introduced into the accumulator 4 loops 5. In the process of squeaking the required photo-telegraph signal recorded on magnetic tape 2, it is pulled out of the accumulator 4 loops 5 or the introduction of a forward and rewind mechanism 11 into it. In the process of reproducing this phototelegraphic signal by a block of 9 magnetic heads of reproduction, the movement mechanism 7 provides movement of the magnetic tape 2 at a nominal speed.

5 The invention allows to significantly reduce the dependence of the processes of magnetic recording and reproducing information by the first and second nodes of magnetic heads.

0 The invention can be used in magnetic recording and playback of both analog and digital information.
