Description
Дл магнитной записи звука на ферромагнитной проволоке н воспроизведени этой записи примен ютс головки закрытого тнпа, у которых катушка имеет большое число витков. Недостаток этих головок заключаетс в том, что дл их зар дки необходимо полностью перематывать звуконосители с одного барабана на другой. Это затрудн ет эксплуатацию аппарата.For magnetic recording of sound on a ferromagnetic wire and reproducing this recording, closed-loop heads are used, in which the coil has a large number of turns. The disadvantage of these heads is that in order to charge them, it is necessary to completely rewind the sound carriers from one drum to another. This makes it difficult to operate the machine.
В описываемой головке этот недостаток устранен тем, что применена катушка, у которой, с целью облегчени зар дки, обмотка выполнена в виде одного витка с зазором дл пропуска звукоснимател .In the described head, this disadvantage is eliminated by the fact that a coil is used in which, in order to facilitate charging, the winding is made in the form of a single turn with a gap for the pickup to pass.
На фиг. 1 показана обмотка катушки; на фиг. 2 - обш,нй внд головки .FIG. 1 shows a coil winding; in fig. 2 - obsh, ny vnd heads.
Обмотка катушки состоит из большого количества нзолированных одиночных витков /, которые соедин ютс между собой параллельно путем припаивани к двум пластинкам 2. Соединенный таким образом пакет проводников укрепл етс на каркасе 5. Каркас от обычных отличаетс тем, что на одной из его сторон вдоль нродольной оси имеетс узка щель 4, шириной 0,3-0,5 мм в которую вкладываетс звуконоситель.The coil winding consists of a large number of nzolated single coils /, which are interconnected in parallel by soldering to two plates 2. A package of conductors connected in this way is fixed on the frame 5. The frame differs from the usual one because on one of its sides along the longitudinal axis there is a narrow slit 4, 0.3-0.5 mm wide into which the sound carrier is embedded.
Изготовленна одновиткова катушка помеш;аетс на сердечнике, который ничем не отличаетс от ранее примен емых в головках закрытого типа.The single turn coil is made on the core, which is no different from the previously used in closed heads.
Предмет изобретени Subject invention
Головка дл магнитной записи и воспроизведени звука, содержаща сердечник из магнитного материала с воздушным зазором и обмотку , внутри которой проходит звуконоситель, отличающа с тем, что, с целью облегчени зар дки головки звуконосителем, обмотка выполнена в виде одного витка с зазором дл вкладывани звуконосител .A magnetic recording and reproducing head comprising a core of magnetic material with an air gap and a winding inside which a sound carrier passes, characterized in that, in order to facilitate charging of the head with a sound carrier, the winding is made in the form of a single turn with a gap for inserting the sound carrier.
