I HAVE COPIED MUSIC FROM MY MINIDISC VIA

It is much easier to use an analog mixer and microphone thru the mixer. I would plug the microphone into the mike input on the mixer and then the Karaoke machine to stereo LINE inputs on the the Mixer, then Mixer Output or Tape Output on the mixer to analog LINE IN on the MiniDisc recorder.
Let me know if you need more info.

If you look on the back of some 5-disc CD players, you will see a similar optical output plug. You can plug an "optical" (fiber optic) cable between the CD player and the MiniDisc recorder and record using the 'optical' input. You will have a perfect copy, but note that you cannot now make a copy of this copy - it's a one-time only copy when you record digitally thru the optical or RCA digital input jack. Let me know if this helps. Good luck. I think MiniDiscs are about the handiest music format ever.

Like all home recorders, yours will not let you digitally record digital originals. The Serial Copy Management System (SCMS) is designed to prevent piracy.

Unfortunately it also means you cannot copy your own digital originals digitally.

Record them via the analog input. It will sound fine.

C-17 means whatever you are trying to record is a second generation digital recording which has had inserted an anti copy signal to prevent another digital copy from being made, hook the source up to your recorder via analog cables to make a copy.

my pc is windows 7 and that dosent work in mz-n510

you have installed the Sony software (you don't have the driver... http://esupport.sony.com/LA/perl/swu-list.pl?mdl=MZN510 enter your OS and download, and you have the USB data cable or optical cable (optical is recommended)? plug AC adapter to mini. Open two windows of my computer. go to your music folder and copy / paste or click and drag to mini disc.

happy recordings

Your problem is that MiniDisc is only a one-way street. Music can be copied from another device or (with a Net MiniDisc) digitally transferred from a host pc onto the MD unit, but not the other way around. Confusion arises because in older versions of Sony SonicStage, music could be checked in and out of the device. When checking out, a copy was made onto MD along with a digital rights licence. The original stayed on the host pc and could only be checked out on three additional devices at any one time. When checking music back in, the device simply erased the digital copy on the MD and transferred the licence data back into the host pc, so that one of the four possible copies was restored and made available for further check-outs. Later SonicStage software abandoned this clumsy "check-in, check-out" process but tracks downloaded onto an MD under the old process could not even be erased from an MD until checked back in again.

There is no hack or modification for this; the hardware and firmware simply is not provided in the MiniDisc system design to allow it.

A later and brief-lived development of the system was the Hi MiniDisc (Hi-MD). This does allow the user to upload material recorded onto the device to a host pc, but still does not allow you to upload material from pre-recorded sources or from your old collection. This is because uploads are possible only when using a dedicated 1GB Hi-MD, when the system uses older legacy MD's it uses different processing circuitry with all the old limitations.

Your only option is analogue transfer in real time. You can improve the quality if you are able to use the optical transfer provided on some models, you'll also find that some models allow you to bypass the output volume circuitry on the headphone jack by setting it to line output. But there is no way to speed up the transfers, sorry.

I hope that you have found my posting to be of use, you may also wish to search my other MiniDisc answers for additional information which you might find to be of further assistance to you. All that I ask in return is that you take a moment to rate my answer.

It isn't possible to transfer your music from a minidisc to a computer...Sony made it so you can only transfer from a computer to the minidisc...Very bad engineering, but that is the bad news...

Your analogue music will have been recorded digitally by your machine.

Digital transfers are only possible from the host pc/Mac to the player and not the other way around.

But you can transfer the audio signal by connecting the headphone output to the Mac audio input; look into the Minidisc player menu and you can set the headphone socket to "line" which bypasses the volume control circuits for better quality, your computer will then re-convert the analogue input into a digital signal with a small loss of quality.

I don't think this is designated a "Net-MD" - is it? If so, by using the proprietary software (Sonic Stage), recordings can be transferred from the computer via USB to the MD unit - and back again.

You won't be able to "transfer" using a USB cable if the recordings didn't originate via Sonic stage. But you can record them in real time using Cool Edit, Adobe Audition or Audacity (free proggie!). This is the only way of transferring music from any non-USB equipped MD unit, or any MD unit that made the recordings with a mic or using line-in.
