摘要：We have evaluated the reproduction characteristics of a magnetoresistive (MR) head for a rotary drum in a helical-scan tape system. This MR head was developed for use in a high-capacity tape storage system that has a high data transfer rate and uses a small cassette. Various experimental thin-magnetic-layer metal evaporated (ME) tapes suitable for the MR head, whose magnetic layer thickness is 0.1 μm or less, have been made, and our evaluation was done using such tapes. We found the output voltage of the MR head was 20 times that of an inductive head, and an areal recording density of 1.2 Gbit/ inch² was feasible with the combination of the MR head and the thin-magnetic-layer ME tapes. Moreover, the pulse width and CN ratio showed that the optimum value of Brδ, the product of remanent flux density and magnetic layer thickness of the tape, for the trial MR head was from 140 to 220 G·μm.
