It seems to me that it would be better to have a wider read head: if the drive needs to write n physical tracks at once, why not read n at once too?

it doesn't write n tracks in one pass, what it does is that it overlaps the tracks the way a row of shingles overlaps the row before them. This means that you can't just write wherever you want to, if you want to write a track you have to write the track that partially overlaps that track, the track that partially overlaps, the second track, etc.

it still takes n rotations of the media to write n tracks
