РЬобретение относитс  к области магнитной заниси.The invention relates to the magnetic field.

Известны ленты дл  обработки рабочей новерхности магнитной головки, содержащие основу из полиэтилентерефталата и абразивный рабочий слой из алмазн;-дх частиц, распределенных в св зуюпдем веществе. Однако известные ленты не обеспечивают требуемой точности обработки рабочей поверхности.Ribbons for treating the working surface of the magnetic head are known, which contain a base of polyethylene terephthalate and an abrasive working layer of diamond-dx particles distributed in the bond between the substance. However, the known tape does not provide the required accuracy of processing the working surface.

Дл  увеличени  точности обработки рабочей поверхности магнитной головки в предлагаемой ленте св зующее вещество абразивного рабочего сло  состоит из смеси поливинилбутирал  и резольной фенолоформальдегидной смолы, наход щихс  в соотношении 1 : 1 по весу.To increase the machining accuracy of the working surface of the magnetic head in the proposed tape, the binder of the abrasive working layer consists of a mixture of polyvinyl butyral and rezol phenol-formaldehyde resin, which are in a 1: 1 ratio by weight.

На чертеже показан вариант предлагаемой ленты, содерл ащей гибкую основу / из полиэтилентерефталата , имеющую толщину 20-50 мкм. На ocBOiBe 1 укреллаи абраэивный рабочий слой, состо щий из св зующегоThe drawing shows a variant of the proposed tape containing a flexible base / polyethylene terephthalate, having a thickness of 20-50 microns. On ocBOiBe 1 ukrelai and abrasive working layer consisting of a binder

вещества 2, в котором распределены алмазные частицы 3, имеющие размеры, равные 0,1-7,0 м.км. Св зующее вещество 2 абразивного рабочего сло  состоит из смеси поливинилбутирал  и резольной фенолоформальдегидной смолы, вз тых в соотношении 1:1 по весу.substance 2, in which the diamond particles 3 are distributed, having a size of 0.1-7.0 m. Binder 2 of the abrasive working layer consists of a mixture of polyvinyl butyral and rezol phenol-formaldehyde resin, taken in a 1: 1 ratio by weight.
