Abstract

This article describes a new head structure which has more than one active gap. A double-gap head structure is analyzed by computer analysis for 2-7 code recording. The analysis results show about 33% improvement in high frequency resolution over the normal single-gap ferrite head. It is also shown that a double-gap head gives a lower peak-shift than a single-gap head at relatively high density. (Image Omitted)
