- Why use CD-R or DVD-R when Blu Ray products including the M-Disc can storage more than one thousand times the data (of the former) one each disc?
Some thoughts.

Minidisc was 140mb. The last generation had 1GB discs and could write ~300mb to original minidiscs. Great video
As I recall, you could use a regular dvd writer to write mini-DVDs, but it had to have the physical means to do so, such as mounting the disk directly to the spindle, not just dropping the disk into a tray or sliding it into a slot. I have some mini-DVDs that I wrote a number of years back for my tax returns and I didn’t get a special drive to make them.
Most tray loaders have a second indent for mini DVD. Spindle loaders are basically guaranteed to work. Slot loaders are risky.
Maybe you could just 3d print a sizing adapter for mini DVD, snapping it around it? It would have to be out of a more difficult filament like PC, but I figure that may work if you have the tools and burn at a low speed.
Is there any possibility of there existing rewritable/erable (BD-RE) Blu-ray M-Discs in the future?
I noticed something that nobody talks about. I have CDs I've burned way back in 2003 and the CDs I have labeled with the stickers that cover the entire disk, are the only ones that have zero degradation. Unlabeled CDs I had to throw away.
25GB Blue Ray Disc cheaper than DVD by cost per 1GB.
afaik a lot of full size (5.25 slot, for ATX case) DVD/Bluray burners have a smaller space at the center of the the tray so you can put a mini-dvd in the right place and then close the tray to read it. It has to be horizontal though as there are no little teeth on the side of this space, unlike for the normal sized disks
Yes. I never knew what that indent was for and now it looks like I've got my answer!
If you find a bluray holding 700 GB, let me know. Otherwise, we're still waiting for a disc with 1000x the capacity of a CD-R.
I knew my maths were lousy LOL. 100X, I meant!
@@danielontechNo worries mate. As for the mini-DVD burners, I really don't think you need a separate device for it since burners with spindles can handle them anyway and burners with trays usually have a smaller, inner groove for miniDVDs. I haven't burned one but I have read them in my ordinary tray reader on an old Windows XP machine. GameCube used a variation of miniDVD, by the way.
The reason I burn CD-R and DVD-R is dependant on application. I record and archive live radio and TV as well as VHS, vynil etc particularly family stuff. I have my granddad's reel to reel tapes to archive for example.
Many of this stuff ends up on BD-R DL with ECC files for each disc from dvddisaster. A backup of the contents of each disc is then tarred up onto LTO tape (I work in IT and this stuff is essentially free to me but I'd use a HDD or a second BD-R DL). If dvddisaster is unable to correct a disc, which is unlikely and it's also unlikely a disc fill fail badly is at all unless physically damaged, then and files I cand get off disc, I can recover from tape, and then I can reburn a new disc.
The same tar files also end up in the cloud, but you'll see the shit really should hit the fan for me to recover from there.
But, Many things that I archive also have a Audio CD or DVD Video version created. This is mostly because they are for family, who dont have bd drives but have plenty of dvd players laying about. So although I archive mostly to BD-R plenty of video and audio has a dual existence archived also onto playable CD and DVD.
Fantastic approach if I may say so myself. Would LOVE to play around with tape (my career has involved mostly working at tech startups so I was never in an environment where that was used). And can imagine you're getting some nice cost savings by being able to use their gear and media!
