Description
Дл этого рабоча поверхность головки выполнена с пазом, расположенным между ее нижним основанием и слецукь шчм за ним сердечником, а пластина концентратора, плоскость которой аимодействует с нижней кромкой ленты, помещена в этом пазу одним из своих краев под углом 9О к рабочей поверхности магнитной головки. На чертеже показана конструкци опи сываемого устройства. Магнитна nerfra 1 своей плоскостью соприкасаетс с рабочей поверхностью 2 магнитной головки 3, а нижней кромкой 4 - с плоскостью пластины 5, один край которой расположен в. пазу 6, выполненном на рабочей поверхносй-и 2. Пластина жестко сопр жена с малым основанием 7 концентратора, в который В;ХОдит также к большое осно вание 8. Таким образом, концентратор состоит из двух оснований 7 и S возбуждение же его осуществл етс отпьез преобразователей 9, зафиксированных пр помощи гайки Ю. При подаче на пьезопреобразователи напр жени ультразвуковой частоты в концентраторе воз1Шкает сто ча полувол на продольных колебаний. Так: как сечение оснований концентратора разное, то малое основание 7 колеблетс в про дольном направлении с большей амплитудой по сравненик с основа:нием 8. Тог да через пластину 5 на ленту 1 начинают передаватьс колебани этой же частоты и амплитуды. Дл движущейс ленч ты эти колебани с точки зрени линейности канала записи и воспр оизведени не , но они создают микроподушку из воздуха между лентой и рабо чей поверхностью головки. , В результате отсутстви непосредственного контакта между лентой и головкой исчезает эффект сползани (дрейфа) ленты по рабочей поверхности головки, что всегдаFor this, the working surface of the head is made with a groove located between its lower base and a slit ball behind it, with the core, and the concentrator plate, whose plane interacts with the lower edge of the tape, is placed in this groove with one of its edges at an angle of 9О to the working surface of the magnetic head. The drawing shows the design of the described device. The magnetic nerfra 1 with its plane is in contact with the working surface 2 of the magnetic head 3, and the lower edge 4 with the plane of the plate 5, one edge of which is located at. a groove 6 made on the working surface 2. The plate is rigidly joined to the small base 7 of the concentrator, into which B; it also goes to the large base 8. Thus, the concentrator consists of two bases 7 and S excites it. transducers 9, fixed with the help of a nut Y. When applying ultrasonic frequency voltage to the piezoelectric transducers in the hub, a hundred-half-wave pivots on longitudinal vibrations. Thus, since the section of the bases of the concentrator is different, the small base 7 oscillates in the longitudinal direction with a larger amplitude compared to the base: 8. 8. Then, through the plate 5, the vibrations of the same frequency and amplitude begin to be transmitted to the tape 1. For moving lunch, these fluctuations are not from the point of view of linearity of the recording channel and playback, but they create a micro-pillow from the air between the tape and the working surface of the head. As a result of the absence of direct contact between the tape and the head, the effect of slipping (drift) of the tape along the working surface of the head disappears, which is always
