5 gig hi-md minidiscs

[DrSiddons]

After drilling into the forums, I came across a posting in which the writer stated that a hi-md minidisc could hold up to 5 gigs of data.

Is this possible?

Thanks in advance.

Theoretically, maby it is, but not with the current tecnology of Hi-MD

(Mainy Hi-MD only supporting FAT file systems that is limited to 1GB)

And with a firmware update, would it be possible without replacing our hi-md players/recorders?

[danielbb90]

I think its hardware too,

Maby it would be possable with a firmware update, I bet if it was it would push the hardware more than they were designed for and I bet the power life would be reduced to quite a major loss...

(If all Hi-MD players are compatable with firware updates in the first place)

Hi Guis;

I think that 5 GB could be possible in case of new format of MD/HI-MD, that involves new lend and new laser, like blue ray technology.

I hope that if one day Sony produces MD whit this technology it will be compatible both with standard MD and HI-MD.

For me 1GB are very practical for holding music,45 Hours (atrac3plus 48KB) or 7 Hours and 55 minutes (Hi-SP) are still enough for me, and for and inexpensive disk, about 6 euros each disk, are perfect.But maiby for others stuffs 1Gb are a not ok.

FAT partitions are limited up to 2GB,32kb each cluster, for biger partitions (lager than 2GB) FAT32 is required, or other file sistems like NTFS or RAISER (Linux).

Ahh it was 2GB (FAT formating) lol still the same problems

5GB requires new hardware, I think thats final whatever the case! lol

Completely agree with you taking into account that quality sound of ATRAC3PLUS 256 is really very very good . But you know, dreaming is free

This is down to the wavelength of the laser and the chemical construction of the layers on the disc. If it's possible to make them you can bet your pension it won't be possible to make them fully backwards compatible.

So, the answer is NO. It's not possible, it will never happen.

I am really sorry to cause such confusion (it was me who wrote about 5 Gb), but I only stated that with current technologies it is possible to put 5 Gb on a minidisc-SIZED optical disc. Probably even more. Remember Blu-ray.

But there is no way to make it work with existing [Hi]MDs (both media and devices). And, most probably, there will never be such a way.

And now for some fun. If you compare MD and HiMD specifications & technology, you will easily find out that IT IS currently possible to record about 1.3 Gb on a standard commercially available 700 Mb CD-RW disc. Not that such recorders (or readers) will ever be produced. The idea behind that is exactly the one used to format old MDs in HiMD mode (more efficient modulation and finer laser beam).
