OK, I got myself a scanner for ease. 
For details, I find 600DPI is usually plentiful for certainty. For the Mould SID on transparent discs it appears useful to have a black background instead of the typical white from the scanner (IMG_20240524_171543.jpg & DiabloIII preview).
I found an IR torch is still a good choice for PS1 scans but used from a side angle so it only casts across the disc ( IMG_20240524_171708.jpg ). Directly pointing the IR torch at the disc just makes for a massive white light section. It still takes a little testing to get right but easily captures the mould too (BigRaceUSA disc). It also helped me confirm my Gran Turismo disc doesn't have have a mould stamp despite the umpteen different angles and tests I tried up to 1200DPI!
Thanks folks. I found Manual Camera DSLR Lite app for Android which has the torch option too. Really odd thing with Open Camera is it puts the screen brightest fully up while in use and sometimes presents a far better preview than the picture it takes!
Interesting with the IR: tried a remote and got a glimpse as it flashed, so understand.

At the right angle, you can see the ringcodes like in the image attached. It can take a bit of trial-and-error to get the exact angle, but I've found it to be the easiest way.
Thanks. No iPhone but several old phones lying around - will have to keep trying.

I used to have a flatbed scanner but it was too bulky to keep around (being part of an inkjet printer that didn't print). 
Hi,
Just looking for any tips on visually reading PS1 discs especially. Currently gaining confidence with reading CDs (mainly PC which I'm not finding any matches because that's the wild west of disc pressing) but have a match on PAL Gran Turismo (#81). Obviously another verification isn't particularly needed but best to find something solid to build from. With & without front or backlighting it's difficult but my (aging) eyes aren't finding anything regardless. Any tips?
Tried hunting for a previous discussion (surely there is one!) but fell flat. Pointers to old discussions obviously welcome: no need to repeat. 
Interesting, thanks.
Any tips on reading the ring codes from PSX discs that are black? The only one I can see is the stamped one.
I've got a small number of such items also. Definitely curious if they're wanted.

There's a difference between having an MCN/ISRC filled with zeros and having none at all. Most discs have different data where those would be, rather than zeros. If a disc actually has zeros, then it'd be correct, but probably they don't even have zeros and cd-info is just wrong.
You got me curious so I went hunting.

3.7.1. Compact Disc
In the case of Compact Discs the ISRCs and other PQ-data are encoded in the disc sub-code (Q channel) in the disc mastering process. For this reason, ISRCs must be encoded for each track in the Pre-Master for CD. The ISRC codes, together with the Digital Copy Prohibited flag, and the relevant point of sale code, such as EAN/UPC should be inserted on the Pre-Master during the pre-mastering process from the original Master.
http://en.wikipedia.org/wiki/Compact_Disc_subcode
Channel Q is used for control purposes of more sophisticated players. It has three different modes, but with a common structure for all of them.[1]
Control bits: The first four bits are used for control, each being a flag for a different feature:
Four-channel compact disc digital audio flag: indicates that the track uses four-channel audio (applies only to CD-DA). This is very rarely used on Compact Discs.
Data flag: Indicates that this track contains data (rather than audio). Can be used for muting in audio CD players. Not used in the original CD-DA standard, added in the CD-ROM specifications.
Copy protection flag: Used by the Serial Copy Management System to indicate permission to digitally copy the track.
Pre-emphasis flag: The audio track was recorded with pre-emphasis (applies only to CD-DA). Used very rarely on Compact Discs.
Mode bits: The next four bits indicate the mode of the Q channel, which can vary from 1 to 3, and define the structure and contents of the next bits.
Data bits: The next 72 bits contain Q-channel data, and their structure depends on the mode define in the previous bits.
Q Mode 1: In this mode, the data bits contain the Table of Contents of the session (if the Q channel is in the lead-in area), or timing information for the current track (if the Q channel is in the program and lead-out areas of a session).
Q Mode 2: In this mode, the data bits contain the Media Catalog Number (MCN) of the disc.
Q Mode 3: In this mode, the data bits contain an International Standard Recording Code (ISRC) for each track (applicable to CD-DA only). The ISRC is used by the media industry, and contains information about the country of origin, the year of publication, owner of the rights, as well as a serial number.
Cyclic redundancy check bits: The last 16 bits contain an error detection code computed over the previous bits of the channel.
... understood, thanks mock. cd-info is just wrongly outputting this info for non-CDDA.
