Abstract

A high density magnetic recording for a helical-scan tape recorder has been developed. Tape-head characteristics and a PRML-class 1 detecting method with adaptive digital equalization are discussed and a new auto tracking following technology has been proposed. Using these technologies, we have achieved symbol error rate less than 1*10E-5 at an area density of 268 Mbit/inch². As a result, we have successfully demonstrated an advanced tape streamer with a transfer rate of 24 Mbps and a capacity per cassette of 25 GB
