How fast do the new USB Minidiscs transfer really?

Like the Sony N1 or the 707.

Is it really painless? Does the transfer software convert MP3 to ATRAC?
Can you transfer recordings to the PC quickly?

EDIT:

OK - Koing and whoever else, here's what you wanted.

I bought an MZ-N707 with OpenMG Jukebox V2.2.

Transfer from PC to MD: Standard recording (SP) from 192Kbps MP3 is pretty much real time when you take into account the conversion time (on a 1.33Ghz Athlon). Bad. I haven't tried 2x and 4x LP because I'm quite fussy about sound quality and some of my other MD decks aren't LP compatible anyway.

This transfer process is called checkout, and there is a limit on how many times you can checkout a track from a PC (3). I have no way of telling whether this checkout code affects the original MP3 file since I haven't installed the software on my other PC's yet, but if it does make any changes to my MP3 files to enable this copy protection, then I'm suing. For the moment though, deleting the song from OpenMG Jukebox and re-importing it seems to reset the count.

The transfer/conversion procedure is also very buggy. I've tried to make 5 MD's and 2 of them were unplayable - the tracks would come up on the player but no sound would come out, but not for all of the tracks on the disc - 2 tracks worked on one, just one on the other. I tried the offending discs in my MD decks but they wouldn't play either - so a problem at the conversion process.

Transfer from MD to PC: It denies me access to all the tracks that I've recorded on my MD decks, because it only supports tracks that have been 'checked out' using the above method. Even if it were possible, it can't be converted into a WAV file for editing. Useless.

<rant>
On the whole, I'm disappointed about the USB facility. Too much functionality has, in my view, been sacrificed to placate the RIAA, and especially their lawyers, who are a bunch of greedy, scheming fvcking bastards. Did you hear about what they tried to introduce on the back of the anti-terrorism legistlation? I'd personally grab an Arab fundamentalist, arm him to the teeth, point him in their direction, and say "look, a bunch of infidel American Zionists, have fun..."
</rant>

I needed a Minidisc player anyway, and as a 'traditional' MD player/recorder the MZ-N707 is very pleasant. Otherwise I would have taken this back to the shop, as the PC integration features are next to useless for my needs. The microphone socket means that I can use it for recording conferences, and the LP facility means that no matter how long the speaker drones on (and no matter how long I go to sleep), it's all on the disc. The only thing I could miss compared to other MD units I've had is a backlit display on the remote.

A minor point, but too many of the OpenMG Jukebox software messages are in Japlish. With a 'global' company like Sony, they should have picked this up.

The facility to simply alter track and disc titles from the OpenMG software is nice, but I can do that simply through my main MD deck as well (it has a PS/2 keyboard socket on it)

The fact that the player uses standard Nicads also is good.

I'd give it 7 out of 10 as a regular MD recorder/player, and 2 out of 10 as an Internet music device.

USB 1.x speed tops out at 12 megabits, which is 1.5 megabytes per second. So you're never going to top that, no matter what.

That would of course be optimal conditions, with the device connected directly to the PC, & having the entire controller to itself.

Urrrr, that's very handy to know if I didn't know it already Viper, but the Minidisc transport probably has a recording speed considerably slower... That speed is what I want to know.

I know its 16x speed they say but I want REAL times in minutes and seconds. They say its 16x with normal compressioin that I am use to and up to 32x speed with compressioin of the music.

for anyone who has one.

Someone correct me if I'm wrong.

The Sony minidisc USB doggle is basically a little soundcard that just converts audio to an optical digital output. Basically, you're recording the audio digitally into the TOS input of the minidisc. Mp3's don't really "transfer" pe se, but plays back plays back in real time and is recorded digitally into the minidisc recorder, which is then converted to Sony's ATRAC in real time. Because it's a Sony (they 0wN a recording label), I don't think you can "transfer" or record it back from minidisc to PC digitally. You can record it back into the PC by means of analog, but your sound degrades.

They do have that, USB sound devices I mean, with current MD models. The fastest you can record with that is real-time (1x).
NetMD is different, though; the USB link goes directly to the MD unit. As I understand it, software on the PC converts what-have-you to ATRAC, then pumps the ATRAC data directly onto the disc via the USB link.

[edit] As soon as Sony starts shipping them, I'll have an MZ-N707 in my hot little hands. I can post a 'review' about it then if anyone is that interested.

sweet DO post the review as I want to see what it ACTUALLY is like:D

I read that it can do 1.8 recording in SP but at this other site it says 2-4x speed SP. SP is the only recording mode I am interested in. LP2 can do 16x but then the bit rate of the sound is half of SP. I want good sounds as I have pretty good headphones........

thanks for that review.

I'll hope to try the top end model sometime and see how it works for me.

Very good to hear from a *real* consumer and nto a site about its *real abilities*.
