Description
(54) РАБОЧИЙ СЛОЙ НОСИТЕЛЯ МАГНИТНОЙ ЗАПИСИ(54) WORKING LAYER OF THE MEDIA MAGNETIC RECORDING
заторауотверждени и 55,0 растворителей .. ;mash and 55.0 solvents ..;
Предг агаемый рабочий слой о0еспе|4 tBaeT высокую адгезию к немагнитной полимерной пленке, что позвол ет в значительной степени повысить проч , ность носител магнитной записи. Кроме того, этот рабочий слой.обладает высокой эластичностью, обеспечиваюией его надежное прилегание к магнитным головкс1М в процессе записи и воспроизведени .The proposed working layer is a high-adhesion to a non-magnetic polymer film, which allows a considerable increase in the strength of the magnetic recording carrier. In addition, this working layer has a high elasticity, ensuring its reliable fit to the magnetic head in the process of recording and reproduction.
