I have some of :, Some cylinders, some Diamond Discs, Some standard 78s, vinyls in all sizes, reel-to-reel tapes, cassettes, 8-Track cartridges, CDs, USB sticks. Reel-to-Reel Video, VHS, Beta, DVD, 8mm film, Super 8 film, 16mm film.
No 35mm film or above. and Minidiscs in two formats.
Evolution rather than planned obsolescence, I think.
When I listen to the cylinders and most of the DIamond Discs, I don't usually appreciate the recorded material. Same with a lot of the 78s. I guess the popular taste changes over time. I enjoy some of the music from about 1920, probably nothing before.
I hardly play a DVD these days because I've been finding enough old movies on the live free to air TV channels , and they're repeating them a bit in very short time.
Maybe its the hot climate, having a tape curl problem with cassettes. Only some. Of course the pressure pads fall off, and if they are foam rubber they decompose. And sometimes the splices on the leaders come unstuck.
I have three vinyl record players with which you drop the disc into the door and close it to play. I haven't gotten around to getting any of them working yet, I acquired them about ten years ago when a colleague closed up shop. I started on one, and needed a belt to be ordered and never got back to it.
In the collection there's a portable dual-cassette-radio. in which you insert the cassettes one on top of the other, that is to say, the spool-carriers for the A and B cassette share a common spindle. You need to remove cassette B to extract cassette A. I haven't gotten around to that one yet. Imagine the trouble if cassette A's tape comes off the spool and wraps around the capstan - Dremel with a circular saw needed to demolish the tapes.
Oh, yes, I have I think three Edison cylinder Dictation Machines. And a couple of U-Matic VCRs. Only about a quarter of the collection working.
There's a computer with a floppy disc about 8 or 9 inches. And theres another one that uses Sinclair tape cartridges that work like an 8-Track but are micro-cassette size.
I've always wanted a Nipkow Disc Baird Tv but haven't found one, probably couldn't afford it anyway. I thought there should've been more of them about in the UK. It'd have to be a table model to get it to Aust. affordably. I'd make up a mechanical scanner to provide a signal to feed it.
But I think we're off-topic......
