Ive got a traxdata compact disc recorder, i'm unable to finalize disc

There are a few possible reasons why your JVC 150 DVD recorder may be unable to finish a disc or is displaying an error message indicating that a disc is an ad:
Compatibility of the disc: Not all DVD recorders are compatible with all DVDs.
Your JVC 150 DVD recorder might not be compatible with the DVDs you've used for years.
A dirty lens may prevent the DVD recorder from adequately reading the disc.
Even if a lens cleaner helped, if the issue still exists, it might be required to have the lens cleaned by a trained expert.
The CD might have been scratched, damaged, or otherwise corrupted, rendering it unreadable.
Firmware issue: The firmware of the DVD recorder may be outdated or malfunctioning, causing it to not be able to read or finalize certain discs
Hardware issue: There may be an issue with the hardware of the DVD recorder such as a malfunctioning laser head or reading mechanism that is preventing it from reading or finalizing discs.

First to confirm if its a transport problem play a CD from track 1 to the last. If it is not getting stuck and smoothly plays till the end -- transport is OK. The same laser unit which reads the disc also writes. But when it writes the laser intensity is several times higher and the unit runs very hot. And old unit will start to misbehave due to the heat. TIME FOR REPLACING THE DRIVE UNIT.

Philips CDR 870 is designed to RECORD with ONLY Audio or Music CD-R or CD-RW discs !!
The word(s) Audio Or Music MUST be written somewhere on the Cd disc or Cd Covers.
Computer CD-R and CD-RW discs will NOT Record on this recorder !!
My experience of GOOD Audio/Music discs : Philips,Sony,Traxdata,Verbatum
My experience of BAD Audio/Music discs : ALL unbranded discs, Maxell,TDK

oops....something happened during the finalizing process and it failed. Hope you had a back-up in your computer of the disk. It doesn't need to be finalized to have it in the computer, just in case this happens. Looks like your disc got erased.

You can finalize a CD-R anytime you want to but it won't PLAY in a CD player until you do. It will play in another CD recorder, though.

Check the setup. You have "automatically finalize disk" selected.

click the set up button on your remote, then click on disc set up, and then finalize disc. it takes a while to finalize.

Are you using the correct disc type??

The manual states that only discs that are labeled:

"Compact Digital Audio Disc Recordable" (Audio CDR)

*or*

"Compact Digital Audio Disc Rewritable" (Audio CD-RW) can be used.

The popular discs labeled "Compact Recordable" and Compact Disc "Rewritable" are for use in computers, and can NOT be used on the recorder.

Page 16 of the manual shows the graphic of the logos detailed above. The manual can be downloaded for free below:

If you can see recording on the flip side..it is either a disc patch fix (software) obtained thru Go Video..or find another go video recorder to finalize it..you might try unplugging the unit for a minute or two..and try it again...

There actually is a recommended list on Lite-on website but I have used bulk-paq, ridisk and phillips without problems until it stopped reading any alltogether. I recently cleaned it with a DVD cleaner disk and its working properly again. Also on the website is a download for updated firmware which may help in your case.
