Abstract

PURPOSE: To relatively inexpensively manufacture a laminated magnetic recording tape having less irregular pin holes and thickness, and uniform magnetically recording performance over the entire recording locations by detecting the irregularity of the thickness of the magnetic layer provided in advance on the tape and providing a special upper layer on the magnetic layer.
