Title: Detection of track width in magnetic recording/ reproducing device utilizing rotary head
Inventor: AOKI TSUKASA
IPC: G11B5/56
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To detect the track width without destructively analyzing a magnetic tape by holding the scanning amplitude value of a specific track of a measuring magnetic tape as a positional function, obtaining the position where the maximum value of this function in the track width becoming equal to the result of the multiplication with a specific calibration factor, and making the track width of the measuring magnetic tape correspond to the positional value. SOLUTION: A test tape is set to a DSS(digital data storage), and output data of an A/D converter 13 is processed by the same method as in the case of a reference magnetic tape to obtain a characteristic curve g (x) against the position x of the rotary head. Next, the maximum value C of an output value of the A/D converter 13 is obtained, and the already obtained calibration factor K is multiplied against this maximum value C to calculate D=K×C. Then, the position x1, x2 of points becoming to the output D are read out from the obtained characteristic curve g (x). Thus, the value of |x2-x1| is measured as the track width.
