, the sampling speed of the pressure signal is 1 to 6, which is determined by the processing frequency.
#! Convert the angle of the wind to the angle of the beak E1. Therefore, the characteristics of the magnetic disk (difference between positive and negative envelopes)
and its physical location. In step 32, the above-mentioned difference and angle 1° are determined using the sine and cosine, and are displayed on the black display device 14 shown in FIG. From the display in Figure 1, the difference in force (/J1 Sakuna Mate 0 and Kabe 1/2) is approximately 30% of the track that was contributed. The brightness of the circle representing each track may be modulated according to the structure of each track obtained in step 28 of the ggS diagram, where the magnetic medium applied to the magnetic disk is not uniform. According to this representation, the characteristics and physical properties of all tracks can be You can see at a glance whether it is related to the target position.
