A lot of the young (or younger) people these days does not know what a cassette is. It is something like this.
It has a tape with a kind of a magnetic layer on it which has music (data) encoded on it.
In an audio cassette, you have to play from the beginning, and you cannot just skip to the next song. You fast forward the player, so that the tape reel rotates fast, and then stop the fast forward and play it to check if you have stopped in the correct place. Although there were some high end players which can sense the silence between the two adjacent tracks and stop it automatically, but seeking to the next song was purely a skill. Also, no random jumping, just sequential. This cassette has 11 songs by John Denver.
A magnetic reader can read the audio and play it (an audio cassette player). This is a cassette which I used to listen at home more than a decade ago, possible fifteen years ago. I got it out today and played it. Once one side has ended it felt indescribably good to take the cassette physically out and change the sides (which you have to do). This was fantastic.
I kind of like all the old stuff. I have an old Aiwa Walkman (portable audio cassette player), Intel 80486 system, and Intel Pentium MMX, an Intel Pentium D, an AMD Athlon X2, old iPods, 3.5 and 5.25 inch floppy disks and their drives. A few very old printers, including the old dot matrix printers, Punched cards and their reader, old physically large hard disk drives which can hold, say, a few hundred megabytes. Also, I believe we still have the old rotary phone, and also Nokia 1100, and a lot of other things, including calculators, memory units, wireless phones and etc. I love all of them and have still preserved all of them. These are fantastic pieces of hardware.
After playing the cassette, I remembered all of these things. After I compared these to the kind of phone I carry, I think still, these things have a greater value than anything. In fact, whatever I have used, and is not being used, is still kept in my home, even if they don’t work, as they record a piece of history and represents.
I am pretty sure, after a few decades, these will be gold.
