CD-R Rot

Here in Bermuda we get a lot of sun and humidity, and CD-Rs do not like either of those things. The life expectancy of CD-Rs in our climate seems to be around five years, after which time they degrade and become unplayable. That said I do have some CD-Rs that were recorded nearly 10 years ago that play fine. Through the years I've tried several brands, and of which the best lasting seems to be TDK. Unfortunately TDK discs are hard to come by now, so I'm using Verbatim and they seem to be pretty good so far. Time will tell as to their long term stability. A few common sense words of advice:

1). Keep the discs out of direct sunlight at all times.
2). Keep discs in Tyvek sleaves to avoid scratching.
3). Where possible store in low humidity environment.
4). Don't touch the playing surfaces.
