Abstract
In a magnetic-tape recorder, tension rollers positioned before and after the tape heads in the tape path have an outer layer of a polyurethane elastomer to absorb vibration of the tape and reduce flutter. Grooves in the elastomer layer enable the effective resilience of the elastomer to be reduced below the bulk value.
