What are the steps needed to unfinalize a cd on a sony rcd-500c/w100 recorder

The "Din Unlock" feature on the Sony RCD-W100 is designed to allow the recording of audio CDs from external analog sources. It is not directly related to the compatibility of the device with different types of CD-R blanks.
If your Sony RCD-W100 is not able to record on newer CD-R blanks, it could be due to a few reasons:
1. Incompatibility: The device may not be compatible with the specific type or brand of CD-R blanks you are using. Different CD-R blanks have varying quality standards, and older recording devices may have limitations in recognizing or writing to certain types of discs.
2. Firmware/Software Update: Older recording devices may not have firmware or software updates available to support newer CD-R formats. Check the Sony support website to see if any updates are available for your specific model.
3. Aging Laser: Over time, the laser in the recording device may deteriorate, making it less effective at recording on CD-R blanks. This is a common issue with aging optical drives.
To address these concerns, you can try the following steps:
1. Update Firmware/Software: Check the Sony support website for any available firmware or software updates for your model. Installing updates may improve the compatibility of the device with newer CD-R blanks.
2. Try Different CD-R Blanks: Experiment with different brands or types of CD-R blanks to see if the device recognizes and records on any of them. Higher-quality CD-R blanks may have better compatibility.
3. Clean or Service the Device: If the device has been in use for ten years, it may benefit from a thorough cleaning or servicing. Dust or debris on the laser lens can affect its performance. Consult the device's user manual or contact Sony support for guidance on cleaning or servicing the unit.
If the above steps do not resolve the issue, it may indicate that the recording device has limitations that prevent it from working with newer CD-R blanks. In such cases, you may need to consider upgrading to a newer recording device that supports the latest technologies and formats.

Changers are notoriously unreliable. You might be dealing with poorly made media or if it happens all the time it could be that the sled positioning motor has to be cleaned and re-greased as something is stopping it from being allowed to finish a TOC write.
First I would look for complaints on the Internet to see if other are having this problem and the solution may be posted.
Otherwise the unit will need to be serviced.

Refer to the user manual RCD-W500C. From page 20 on you will find how to record and the types of recordings you can do.

usually to the TAPE out sockets[coax,optical,RCA,].Im assuming its not video capable.actually,any out sockets on the amp,and IN sockets on the recorder

It wants a CD-R Audio or CD-R Music blank disc to record on. It won't record on CD-R data discs.

You need to use CD-R Music or Audio blanks, not Data. It's part of the spec for home CD recorders to reject blank data disks.

you need to buy audio cd-r, they are a bit more expensive than the other ones, but that is what it needs...then you will be able to record!
