Abstract :
In this paper, the helical-scan tape systems using the shielded MR heads will be discussed. We studied the issues related to the head/tape contact including the thermal asperity and the head wear. The study suggests that these issues can be resolved to the allowable level in the practical system. In this study, we have successfully demonstrated a high recording density using MR heads in these systems
