Description
ненном со вторым рычагом 8, на котором укреплена игла 9. Последн размещена в направл ющей спиральной канавке диска 10, установленного на маховике 11, расположенном соосно дисковому носителю записи 2.with the second lever 8, on which the needle 9 is fastened. The latter is placed in the guide spiral groove of the disk 10 mounted on the flywheel 11 located coaxially with the disk recording medium 2.
Предлагаемое устройство содержит также редуктор 12, св зывающий вращающийс вал 3 с маховиком И и выполненный с передаточным числом, равным отнощению щага спиральной дорожки записи дискового носител записи к шагу направл ющей спиральной канавки диска 10.The proposed device also includes a gearbox 12, which connects the rotating shaft 3 with the flywheel AND and is made with a gear ratio equal to the ratio of the scroll of the recording track of the disk recording medium to the pitch of the guide spiral groove of the disk 10.
В предлагаемом устройстве относительное перемещение воспроизвод щей головки 1 вдоль спиральной дорожки записи обеспечиваетс за счет вращени дискового носител записи 2 и перемещени иглы 9 по направл ющей спиральной канавки диска 10. При этом точность попадани воспроизвод щей головки 1 на спиральную дорожку записи увеличиваетс за счет того, что щаг направл ющей спиральной канавки может во много раз превосходить щаг спиральной дорожки записи.In the device according to the invention, the relative movement of the reproducing head 1 along the spiral recording track is ensured by rotating the disk recording medium 2 and moving the needle 9 along the guide spiral groove of the disk 10. At the same time, the accuracy of the reproducing head 1 on the spiral recording track is increased by that the guide groove of the guide groove can be many times greater than the tape track of the spiral track.
Использование изобретени иозвол ет в значительной степени уменьщить щаг спиральной дорожки записи, а следовательно, и плотность записи. Кроме того, использованиеThe use of the invention makes it possible to significantly reduce the schit of the spiral recording track, and hence the recording density. In addition, the use
изобретени обеспечивает значительную простоту конструкции устройства дл воспроизведени с дискового носител записи. Подобное устройство может найти применение в аппаратуре бесконтактной магнитной записи и воспроизведени .The invention provides a considerable simplicity in the design of a device for reproducing from a disk recording medium. Such a device can be used in non-contact magnetic recording and playback equipment.
