Abstract

Методът и устройството са приложими в изчислителната техника. С метода се постига оползотворя ване на по-голяма информационна площ, а устройството за позициониране е опростено. По метода инфорамционните и маркиращите сигнали се записват от едната страна на гъвкавия дисков магнитен носител, върху едни и същи пътеки, разделени на два сектора, при което информационният сектор е с ъгъл най-малко 330', а маркиращият сектор с ъгъл най-много 30', като честотата на маркиращите сигнали на всеки две съседни пътеки е различна. Устройството съдържа четящ усилвател, два честотноизбирателни блока, два диференциални усилвателя, източник на опорно напрежение и контролен усилвател, свързан с блок за прецизно позициониране на четящата глава. 4 претенции, 4 фигуриThe method and device are applicable in computing. With the method, utilization of a larger information area is achieved, and the positioning device is simplified. In the method, the information and marking signals are recorded on one side of the flexible disk magnetic carrier, on the same tracks divided into two sectors, the information sector having an angle of at least 330' and the marking sector having an angle of at most 30 ', with the frequency of the marking signals on every two adjacent paths being different. The device contains a read amplifier, two frequency selection blocks, two differential amplifiers, a reference voltage source and a control amplifier connected to a block for precise positioning of the read head. 4 claims, 4 figures
