Will there ever be faster CD and DVD discs and writers?

I was thinking about the fact that in the last years I have never seen CDs and DVDs supporting writing/reading speeds higher than 52X and 16X, respectively.

Is this a commercial choice (i.e. manufacturers don't care about optical discs anymore and focus more on flash memories and SSD drives) or a technical limitation (i.e. optical drives cannot support higher writing and reading speeds)?

It's mostly a technical limitation. Put simply, if you spin the disk too fast it starts to become unstable and wobble around or even start to come apart under the sheer stress. At best this means read/write errors - and at worse means the possibility of it coming loose and causing damage.

At 52x speed, the disk is spinning at around 24000 RPM - at around 27000 RPM the disk would start to crack.

KenWood has played with CD-ROMs that use multiple lasers to read several places on the disc at once and then re-compose them into a single stream in firmware. They call this technology TrueX. You're able to read data faster at the same spin rate, but you need to use a more powerful laser (since it's being split), which requires more power and results in more heat.

About a decade ago there were CD drives that used multiple laser beams to read 7 tracks at once for higher performance without having to spin the disk extremely fast. However they were expensive and apparently had reliability problems as well.

It's also worth noting that it isn't just a question of structural integrity of the disk at high RPMs, but also of noise.

15 years back...

"Will there ever be floppy disk with capacity more than 1.44 M?"

"Will there ever be floppy disk with higher read/write speeds?"

(For those who incase don't know, what floppy is: http://en.wikipedia.org/wiki/Floppy_disk)

Today, we don't care for an answer to above questions, simply for the fact that 'flop'pies have flopped.

Now, even CD-DVDs are approaching a similar state & have been replaced by Flash drives & Memory Cards. And in years to come, mechanical Hard Disks will follow the suite & will be completely replaced by SSDs.

The root lies in storage technologies involving mechanical movement/rotation are slow, error prone, require more power, make more noise, generate more heat & will be replaced by their non-mechanical counterparts & technology by next decade.

I personally doubt there will be a lot of work done in making the spin rate or RPMs faster on CDs or DVDs because the main reason to make them faster would be to be able to read or write the data to the disc then store it somewhere or perhaps send it to someone. However with the internet and network speeds getting faster, along with other technologies that allow us to share files to people of our choice, there is little need to make the discs spin faster as other technologies are already much faster than CD's or DVDs in terms of read and write speed.

If you look at the cost of a 2TB WD passport drive they cost around $100 and they fit in the palm of your hand, that beats discs any day for storage and speed, along with durability and portability.

I do think that having a CD or DVD available has its merits, like when you need an OS CD to fix an installation of an operating system, but for sending data there are faster and cheaper ways of doing that these days.

I just thought I would put my two cents in, hope I didn't upset anyone with this comment Cheers
