Saw a disc available on eBay recently that I don't think is in the database here.

It's an 8" CLV disc, Warner Reprise Video Volume #2 [9 38307-6]

What caught my eye though was the disc itself, it's single sided and the dead side has a label printed across the entire surface, much as a CD would.

Also unusual is that the area surrounding the spindle hole is transparent. In fact looking at the picture, with nothing to set the scale, one might take it for a CD (the second picture below shows that that isn't the case though).

I was actually wondering if it might be a polycarbonate disc, like a few PAL releases (but I never heard of any NTSC releases being manufactured by Sonopress using that technique).

Were there many discs like this, where the label covers the whole side?

Just curious!

Had this one years ago, it was full printed like the one you have pictured.
So there are at least 2 out there.

My mistake for saying it's not in the database when it is, I think I included 'sampler' in my search terms and it came up with Vol 1 but not Vol 2...

I see from that it's manufactured by "Nippon Columbia" so that torpedoes my theory of it being a polycarbonate disc - although it has to be said that that clear centre area is fairly unusual for a conventional LD...?

I have a Tenchi Muyo promo 8” like this. It’s only for single sided 8”ers.

I thought these were interesting for a long time as well - they really take the whole “laserdisc is like a big CD” thing to the next level

Unfortunately the LD single format was very uncommon in the US and those Warner samplers were 2 out of the very small selection that was ever released here. That’s why they look particularly unusual to most American LD collectors.

There are plenty of other LD singles released in Japan. I have one, as well as a grippy adapter for them intended for use in certain players that could not handle the CD-style thinness of the disc.
