Cranky noise when recording

[morphy]

Hello all,

My first post here.

I own a NetMD MZN910 ( I think its about 2 years old ) - and recently I tried recording and erasing some of my old minidisc and found that the noise level during the recording and deleting process very loud and cranky.

I don't remember hearing such noises before ... (I haven't used the NetMD for a while now).

However - I've just installed the new SonicStage 3.3 and although it makes some really loud noise during the deleting process - it still works!

I'm just worried about the noises I hear from my NetMD.

Any ideas?

Thanks!

The lubricant on the transport spindle might have dried up and need to be refreshed.

Thanks! Any idea how I can obtain the proper kind of lubricant for the transport spindle? How do I go about applying it?

Sorry for all these questions. I had a look in the manual - nothing on how ot lubricate the spindle.

I just bought a second hand MZ-R700 for spare parts off of Ebay. It actually works but it makes a really loud, high pitched, whirring/spinning noise when first putting the disc in, and when the disc nears its end (I assume it's returning the laser to the "home position"). Also, I noticed there is a short loud motor sound when you go to the last track on a disc, play it, and then hit "back-track" to return to previous tracks. So the machine seems to have problems reversing the laser head.

Here are my theories:

1. The rails the laser head rides on need lubrication with grease.

2. One of the motors is failing (but which one? - there appears to be three of them in there - one to spin the disc, one to drive the worm screw / laser, and the other for what I'm not sure).

3. There is a problem with one of the plastic gears inside the machine, which is causing it to slip (you should be able to detect a problem through visual inspection of the gears).

I opened the machine up and lubricated the rail that is smooth, (I didn't lubricate the 'worm screw' rail - I will have to try that). The sound still persists. Other than that noise, the machine works fairly well. 1 in 10 times it will give me DISC ERROR when recording (especially when writing near the outside of the disc - end of the disc). It also hung a few times when writing updating the TOC. I assume these disc errors could be the result of the laser meeting resistance due to lack of lubrication. For a $30 unit off Ebay meant for spare parts it is actually performing better than I expected...

I just used some spare bearing grease I had left over from my wood lathe downstairs. It's sort of yellowish brown in colour. I also wondered if any of that white computer heat-sink grease I had would have done the trick. I don't know if either of the above are the best to use - ideally you would want whatever that white stuff is that they use in the factory. You don't want to use anything that is too liquid, and could drip onto other components.

You can apply a small amount to a Q-tip or the head of a long pin and get it in there to smear on the rail. This can be done without taking the machine apart, just DON'T GET ANY ON THE LASER OR MAGNETIC HEAD.

Please use the standard white lithium grease. It's often available at your local electronics supply shop. Never use mineral oil based greases, it can break the plastic parts!

I tried lubricating the worm screw. It didn't eliminate the noise in the case of my MZ-R700, so it must be the motor bearings or a gear (but the gears look okay).
