I've got a few caddies that seem to fit in an RRD40 but the only markings on them are a couple of arrows, "COMPACT disc" (on each side of the outside translucent shell) and "LABEL", "DATA" and "Made in Belgium" (on the inner flat-spectacle-frame-like-thingy). There is a group of four over four notches cut out of the front edge that look like they might have some significance. I've only just noticed now on examining one closely that on the other side some types of magnetic media and the little arrow beside it actually looks like a head over platter type symbol. What's that about? I could send you one if nothing turns up in a better location (I'm in Ireland). Regards, Peter Coghlan.

Here's one that looks like mine: http://home.claranet.nl/users/pb0aia/cm/cm201.jpg The Owner's manual is on the web too: http://www.carelife.com/manuals/RDD40_Optical_Drive_Owner_Manual.PDF and that has drawings of the caddy. There's an even better drawing here: http://thedecyears.com/wp-content/uploads/2013/05/VMS-Online-Documentation-… Antonio On 19 November 2014 23:45, Glen Slick <glen.slick at gmail.com> wrote:

It's been a number of years since I've tried to use my RRD40, but iirc, you slip the disc into the "antlers" and then slide that into the plastic caddy. That whole caboodle is then inserted into the RRD40. The internal mechanism somehow grabs the antlers+disc and what you pull out is an empty caddy. To retrieve the disc, you insert the empty caddy into the drive and out it comes with the antlers+disc. Manually removing the disc from the caddy involves squeezing the antlers to free them somehow. I *think* the idea was that your discs would each live permanently in a caddy or inside a drive. Removing the disc from the caddy was quite clunky, iirc. So I presume the extra tabs and sliders and whatnot are there for the drive to do its magic. Antonio
