Description

Изобретение относитс  К области приборостроени , а именно к аппаратуре магнитной записи и воспроизведени  на дисковых носител хThe invention relates to the field of instrumentation, namely to magnetic recording and reproducing apparatus on disk media.

Известны устройства дл  креплени  и перемещени  плавающих магнитных головок, которые содержат упругие держатели, т ги, электромагниты , осуществл ющие перемещение головок. Однако дл  таких устройств характерны сложность и громоздкость подвеса магнитной головки .Devices are known for fastening and moving floating magnetic heads, which contain elastic holders, rods, electromagnets that move the heads. However, such devices are characterized by the complexity and bulkiness of the suspension of the magnetic head.

Цель изобретени  - упрощение подвеса головки.The purpose of the invention is to simplify the suspension of the head.

Это достигаетс  тем, что предлагаемое устройство снабжено плоским пр моугольным пьезокерамическим преобразователем, один узкий конец которого жестко скреплен с упругим держателем, а второй аналогичный конец - с основанием устройства.This is achieved by the fact that the proposed device is equipped with a flat rectangular piezoceramic transducer, one narrow end of which is rigidly fastened to an elastic holder, and the second similar end to the base of the device.

На чертеже схематически показано предлагаемое устройство.The drawing schematically shows the proposed device.

Устройство состоит из магнитной головки 1, установленной наThe device consists of a magnetic head 1 mounted on

ПЛОСКОЙ пружине2 и соединенной через пьезокерамический преобразователь 3-е основанием Л. В результате изменени  уровн  напр жени  посто нной пол рности .на обкладках пьезокерамического преобразовател  происходит его изгиб и с помощью плоской пружины магнитна  головка перемещаетс  в направлении плоскости магнитного диска 5. При от0 ключении обкладок от источника посто нного напр жени  пьезокерамический элемент восстанавливает свою первоначальную форму, а магнитна  головка возвращаетс  в ис5 ходное положение.A FLET spring 2 and a 3rd base L. connected through a piezo-ceramic transducer. As a result of a change in the level of the constant polarity on the plates of the piezo-ceramic transducer, it bends and, with the help of a flat spring, the magnetic head moves in the direction of the magnetic disk 5. When you turn off the plates from a constant voltage source, the piezoceramic element restores its original shape, and the magnetic head returns to its original position.

Предлагаемое устройство позвол ет уменьшить количество деталей , участвующих в перемещении магнитной головки и, следовательно , упростить конструкцию.The proposed device allows to reduce the number of parts involved in the movement of the magnetic head and, consequently, to simplify the design.
