If you wish to explore your compressor pressure switch, and I do recommend that you make yourself familiar with what is inside, make sure first that the compressor power supply is unplugged then go ahead, remove the cover. You want to be sure the power is off as there are live power connections inside the lid.
Discs are sometimes collected at some local recycling centres. To find out where your nearest recycling facilities are, use our handy Recycling Locator tool. Check local CD/DVD recycling. VHS tapes and cassettes are now rarely accepted at recycling centres and are generally sent to landfill. A company called Tip Top Media currently accepts old tapes for disposal but there may be a charge for this so please contact them for more information.
Actually, Shawn, reel-to-reel was just an audio format (I had a Sony to play my KISS albums). VHS and Beta came out about the same time, and laser discs came out between VCR's (VHS or Beta) and DVD's. Strangely enough, laser disc movies came out before cd-audio. Now we've got DVR's of course.
