- An increase in the memory of the storage device is connected, in the first place, to the opposite, with a movable medium
- a preferred embodiment of the invention is that the electromagnet emits a radiant voltage that is not susceptible to physical damage to the environment.
- the proposed embodiment of the invention makes it possible to significantly increase the accuracy of use of the information - ⁇ . - footprint on the carrier (access to your home and its parking). This is due to the decrease in the number of residents of the “hostel-head” business due to the immobility of the latter and the decrease in the value of the registration record.
- One of the variants of the invention in the quality of the source of the electric radiation is using a large amount of
- the proposed version of the device makes it possible to access the unit due to the integral operation of the magnetic and scanning parts
- the magnitude of the induced charge in the incipient is significantly less than that of a known head with a mechanical charge
- 35 magnets offered by the head are made with a subtle thickness. This, in turn, detects the presence of an informational trace in the carrier (submicro- - 6 - the wide width of the home recording) and the closer location of the homestay on the carrier.
- the universal head was equipped with an auto-tracking unit, the outputs of the 5-port are connected to the laser, which is compatible with the electrically
- FIG. 1 illustrates the principle of the storage of the house for the implementation of the invention, according to the invention (accessory); ⁇ ig. 2 - a basic diagram of the operation of the head (view 5 side); ⁇ ig. 3 - ⁇ is the same (view in plan) ⁇ ig. 4 - view ⁇ on ⁇ ig.Z.
- One of the sites of 5 magnetic drive 2 (one of the receiver frames) is converted to a magnetic carrier 6 (magnetic tape) and is connected to a parallel drive.
- a positive magnet 2 part of the service I I installed a source of electromagnetic radiation - modulated laser 7.
- the supply of magnet 2 and the main part of the service I is equipped with a free-wheeling unit 8 (lamp), which is used for 30 communication of part 5 of magneto 2 with 2.
- the Solid 8 has a width equal to at least the length of section 5 of Magnet 2 and is equipped with focussing planed lenses 9, 10, 11.
- the headquarters is also equipped with a scanning element 12 in the airborne acoustically-defective 35-year-old physician at the onset of all-round disruption of the patient.
- Element 12 - 8 - I was upgraded to I so that there is electromagnetic radiation at the exit of lenses 9 that is at a corner of the field of neglect. Having purchased the Skye Element 12 on Option I, I installed the 13 Accelerator Acoustic Wave.
- the head works as follows ..
- magenta houses in an infor- mation track of a moving carrier 6 and a fixed external charge.
- Reading mode The processes in the electronic part of the head are similar to the processes of recording and recording (with the exception of the signals for input synchronization in the auto-processing unit)
- the electronic version of the 4 head in this mode is turned on at the input of an external signal amplifier and it emits an emf of induction ⁇ - 10 _ for the carrier trace of the carrier 6.
- the general technical condition for the implementation of the recording-counting modes is the reduction of the minimum size, the laser radiation is 17 on the 5th stage after 2 mag- nus.
- I- the full layer may be one of the widest methods, for example, it is normal, diffused and others. Evaluation of the technical characteristics of the proposed offer is a method for reading the information on a magnetic carrier and ensuring that it is free of business
- the 2 ° model of disaster ensures that it is operable and efficient in comparison with the known steel. Achieved high density of the short-range • • from 1000 to 10,000 st / mm, which is reduced by a small thickness of the film magnet 2 (0.1-1 mm),
- the proposed invention makes it possible to receive, in the form of a disruptive technical medium, 20 video information systems for mass systems.
- 20 video information systems for mass systems Estimated for use- - 12 - large standard magnetic carriers, equipped with high-performance and efficient operation, the system is equipped with a non-volatile system.
