Default Philips CDR-760 - adjustment

Hi,
I have CDR-760 recorder. The recorder works, but there is a problem with reading of outer tracks and skipping. What do you suggest?
Regards,
f.

Don't adjust anything, give the mechanism a clean. Often a tiny hair wraps itself around a drive restricting the movement.

Lubrication is normally the cause of dirt/hair contamination. Most parts are plastic and don't need "oiling"
There are a few different deck used on that one so some may be plastic, one uses a worm gear covered in grease and another uses a belt that slips.

The mechanism needs a deep cleaning (including lenses). The unit doesn't read its own recordings on CD-RW discs (excluding TOC). The quality of recordings on CD-RW discs is poor (there are C2 errors). I have the service manual, but there is no information about laser pick-up cleaning. Is the isopropyl alcohol safe for lenses?

The official line from Sony many years back was that ISO must not be used on coated optics (typically those with a blue/green tinge) That was a long time ago and I know many do use ISO.

It would be interesting to know what the official recommend is these days for CD/DVD optics. I'm down to my last few ml of Sony lens fluid

Recorder is equipped with CDM-36 mechanism by Philips. Maybe Philips (unlike Sony) "likes" an isopropyl alcohol?
