Improved capstan drive for a tape |
摘要 |
The driving arrangement for a magnetic tape is comprised of a drive shaft having a smooth surface and a pressure roller having a high surface friction coefficient. The circumference of the drive shaft is provided with a thin layer of the borides, nitrides or carbides of a hard metal, which increases the friction resistance of the shaft. This measure reduces the slip, without affecting the proper uniform travel of the tape.
