M-Disc

"The M-DISC™ can withstand temperatures of 176°F (80°C) for a number of days with no effect to the data or the readability of the data in a standard DVD drive.

Can an M-DISC™ withstand UV rays and prolonged exposure to the sun?

M-DISC™ products can withstand the full spectrum of the sun, including UV rays, for days with no effect to the data or the readability of the data. However, prolonged exposure to full sunlight could weaken the plastic substrate leading to brittleness and cracking of the substrate at some point. Of course, a cracked substrate will probably lead to problems reading the data on the disk. In order to maximize archival lifetime, avoid

How do I store an M-DISC™ to maximize the data lifetime? The M-DISC™ is extremely durable and can withstand even extreme environmental conditions (heat, humidity, light, etc.) for a reasonable period of time. However, extreme conditions will shorten the data lifetime of your data and the disc itself.

There are no plans for a CD version of the M-Disc. M-Disc recognizes there are some customers who would like to have an M-Disc that they can play in their CD players, but this market is very small. Also, the cost of making an M-Disc CD would be essentially the same as making an M-Disc DVD, so there would be no cost advantage to an M-Disc CD."

I tried their Bluray out of curiosity as I have no use for any type of recordable disc around the house.

I am not sure who the M-disc is aimed at as they're very expensive, slower than advertised to burn, record once & then the convenient 1000 years lifespan no one will ever be able to confirm

Soon Sony's new UHD Bluray will be released also capable of 100GB and as Sony controls the entertainment market and I can't see any other physical format taking over.

Meanwhile, the good old tape is still the mass storage/backup of choice for IT departments with tapes holding 6.25TB but Sony also announced last year a new 185TB which is "massive" in anyone's books.

When innovations such as this pop up I always think of how imperfect the original CD technology was but now the M-disc appears more of a refinement of existing technology than a revolutionary product and unlikely to grab much market.

While it's around it's also the best choice for long term data storage on disc.

I think it's good to keep innovating, the irrelevant thing today may lead to the next big thing, and I also like technology when it works

However the image on their website seems more for show than content but there are a couple of interesting points.
It shows the humble CD & Gold CD-r lasting 100years as advertised because factory pressed discs don't use organic dyes and the Gold reflective layer in the recordable discs is inert, gold does not react with any chemicals or dyes in this case.



But placing the memory stick/solid state storage as the least reliable does not make sense, electronics these days are very reliable, what fails are mechanical parts wearing out like the traditional platter HDD they rate highly.
