Patent ID: 7486479

Claim:
A magnetic head assembly to record servo signals, that serves for positioning of data recording magnetic heads and data reproducing magnetic heads, on a magnetic tape comprising: a servo signal recording head wherein a sliding surface of said servo signal recording head has a magnetic gap embedded thereon in order to record said servo signals onto the magnetic tape, and a guide block which is set adjacent to a position of up-stream of a line of said magnetic tape passing said servo signal recording head and is slightly set back from said sliding surface of said servo signal recording head so that said magnetic tape slides on an edge of said servo signal recording head and on an outer edge of said guide block, the edge of said servo signal recording head and the outer edge of said guide block being chamfered, wherein a wrap angle (θ 1 ) between said sliding surface of said recording head and a plane formed by the edge of said servo signal recording head and said outer edge of said guide block is in a range of 1.0 to 6.0 degrees.
