I purchased spindles of archival grade CD-R and DVD-R disks for family media archives back around 20 years ago. They were expensive but worthwhile so far.

The reel-to-reel tapes I was transcribing were literally falling apart as they played one last time. Others suffered from the hydroscopic substrate that made them twist and curl. I didn't know about tape baking back then.

I have a media capture kit that includes 4mm and 8mm video, VHS, reel-to-reel and a bunch of adapters. I pipe all the video into a DVD recorder and also an HDMI to USB adapter so I can capture everything twice with one play.
