A problem which occurs mainly on MiniDisc players. Instead of a noticeable pause, The ATRAC encoding sort of blurs over the missing data which results in missing beats among other things. This usually happens with the crappy Memorex gray MiniDiscs which get microscopic little holes in them which make them lose data. Microskipping is much more irritating than regular skipping as you notice subconsciously that something is missing in your song, which makes you lose your train of thought, which is a Bad Thing if you're listening to an MD while doing work/studying
