DEVELOPMENT OF A LOW-FLUTTER MEASUREMENT TAPE

Flutter measurement tapes sold to the professional community may conta in residual levels of time-base errors that are too high to permit acc urate measurements. This study presents a technique for recording tape s with very low residual flutter. A recorder with a transport servo sy stem was used to make high-speed recordings for measurements at standa rd speeds. The recorder has low inherent flutter, exceeding the manufa cturer's specifications. The highspeed technique reveals that a signif icant improvement in the recording of flutter measurement tapes is pos sible, especially when this method is compared to the common procedure of recording at the playback velocity.
