Before looking at how to store them, it's important to understand how cassette tapes work. Inside are two reels, like mini movie reels, connected by a thin strip of magnetic tape and covered by a shell. When you press play, the tape slides on the magnetic head that reads magnetic patterns, which translates to audio. The electrical signals are sent through an amplifier to strengthen the sound, so you hear it more clearly through speaker or headphones.
As long as the cassette tape remains in good order, it will play. But it requires proper storage. One big thing that can impact the life of a cassette tape is temperature, including storing them in an environment that is too hot or cold or where temperature fluctuates often. But it's mainly about humidity too. You should also avoid exposure to sunlight, moisture, dust and dust mites, critters and magnetic fields.
Store them in a cool and dry place, with a temperature at 59 to 73°F and 25-55 percent humidity. Always keep them in their protective cases and wipe down the exterior from time to time to get rid of accumulated dust, even gently using a Q-tip. Don't forget to clean the player's tape heads as well. Play the tapes from time to time, too. Along with losing lubrication, the binder coating can get sticky without use.
Those who grew up in the Blockbuster era know, "be kind, rewind" is a VHS mantra that holds true for cassette tapes as well. When you're done listening, rewind the cassette to the beginning (hopefully using the rewind button versus a pencil) to help minimize stress and uneven winding.
