| titleOfInvention | Tape driving mechanism for magnetic recording apparatus |
| abstract | A tape driving mechanism for a magnetic recording apparatus wherein a capstan (1) is rotated to advance a magnetic tape (3) by pinching the magnetic tape (4) between the capstan (1) and a pinch roller (2). The pinch roller (2) is pressed onto the magnetic tape (3) against the capstan. The capstan surface is coated with a diamond-like carbon film (4) which is smooth and highly wear-resistant. The difference between the tangential speed of the capstan and the tape transfer speed is almost zero; thus, the state of contact is static. A static frictional coefficient between the diamond-like carbon film (4) of the capstan (1) and the magnetic tape (3) is almost equal to twice the static frictional coefficient between the metal surface of the capstan and the magnetic tape in the conventional tape driving mechanism. The tape driving force remains sufficient, if the pressure exerted by the pinch roller (2) is reduced to half the value employed in the conventional tape driving mechanism. The diamond-like carbon film (4) may be coated on a rough surface of the capstan (1). |
