Someone was once telling me that the Earths magnetic pull will damage magnetic media over time, but a way of preventing this is to rotate your mag-media archive by 90 degrees every twelve months. Now the first part I believe, but is there any truth to the second?
P.S.
I have some really old game disks which are probably about twenty years old and still run fine. Only about one percent of my disks (Most are very old) have developed errors.
