ABSTRACT:
A magnetic tape apparatus for reading/writing data from/to a magnetic tape by magnetic heads. The magnetic tape apparatus includes a roller guide for guiding the magnetic tape, a magnetic head assembly having several magnetic heads, and a structure for aligning the magnetic tape to the magnetic heads, wherein the vertical position of the magnetic tape is determined by a lower flange of the roller guide. One feature of the present invention relates to the structure of the roller guide wherein the lower flange is separable from other members of the roller guide such that the vertical position of the magnetic head is the lower flange. Another feature of the present invention is a method for aligning the magnetic heads to a track of the magnetic tape wherein the vertical position of a keen edge formed on the lower flange assembled in the roller guide is detected by microscope.
