Recording In Md-mode On Hi-md

[ROMBUSTERS]

I know this works and ive tried it however I am still dissapointed with the transfer speed (even using crappy small bit-rate/files like LP4). What exactly is the speed limiting factor present in the normal MD mode design that a Hi-MD model cannot correct?

The problem is that the disc cannot be written to any faster. A reformatted 80m disc has a transfer rate of about 5Mb/s and a 1Gb Hi-MD disc is about 10Mb/s (Notice they are Bits not Bites)

Hi-MD is faster than netMD as that has a transfer rate of about 3Mb/s (approx half Hi-MD's reformatted transfer rate as the disc spin at the same speed but store twice as much approx)

no no i realise that 32x is basically the holy grail for the original MD media (formatted old-MD mode). however if you open up SS and put in an Old-MD formatted disc and transfer a song, the song transfers at a reasonable pace but then the unit displays Saving Data with a bunch of dashes which slowly go away. Why is it that this part takes so long? What is it doing if the song is already written? If it writes the TOC when the disc is ejected it cant be doing that right?

When you transfer something to the recorder it will use the anti shock memory as a kind of cache. So the PC can transfer faster at the beginning. these bars indicate how much data has still to be written from the buffer. if the bars are more and more disappearing the whole rest of the data is already in the recorders memory and it should be save to disconnect the usb cable. this is a useful feature if you transfer PC-Files, too.

I given the cost and size of memory these days, I think a real neato feature would be for someone to put 1GB of RAM into a Hi-MD player. Allow it to do ultra quick uploads into this RAM, and then slowly write it all to disk in the background while you are doing other stuff. It would be a little big tricky to do right (you have to trap the disc in the player while it is being written to), but you could also use it as a nice fat anti-shock (never read the same part of a disc twice )... so much goodness potential

Why not go the step further and have something like that edirol 24-bit recorder with a HiMD drive built-in - recordings could be made without any mechanical parts moving, no danger of skipping or loss from shock movements.. the ability to edit either in memory or on disc just as with md/himd already, and finally the option to 'burn' the himd.

Like those hard disc/RAM recorders with CD-Rs or DVD+/-Rs built-in. Only a heck of a lot smaller, and taking way less power.

'Saving Data' means, that the cache is written to the disc.

That could be a few Megabytes.

'Writing System Files' means writing the TOC and the FAT, ~ another Megabyte.

Plus add the seek times, which are not that fast in these portables.

In other words, you have to live with it...
