Last week we started to look at the problem of azimuth alignment on olden compact cassette tape drives, and how this misalignment affects the sound. Let’s now have a look at how azimuth affects the frequencies.
While reading on compact cassette readers (as part of a preliminary study on digitizing archives) I found out that azimuth, or the angle made between the tape and the reading is a considered a big issue, the best case being an azimuth of exactly 90°. I could not, however, quite find what was the effect of varying that angle, even if pretty much everyone agrees that it somehow lessen the tape’s high frequency response. Let’s see how, exactly.
