In 1984 - 1998?

I was thinking of how the CD-Rs could be backed up and even improved upon from the original analogue tape-stock with excellent results for not much outlay other than precious time. And DAT would have been a far better option than CD-R. According to WIKI the CD-R / WO was introduced in 1988, a year after DAT. I'd be very surprised if any of them still work, unlike DAT. Time was, owing to the failure rate of CD-Rs I used to back up my digital archives on cassette; these days SD cards suffice - as well as the ubiquitous H4 (retired from field work, we now use it exclusively for mastering) we run a Zoom R24 for all our main recording work. Not a moving part in the entire operation until it makes it onto the lap-top...

That's a point - has anyone released an album on SD card yet?
