A spot for keeping track of especially cool (informative, fun) videos, photos, scans and other links about record cutting. (You can post them in other sections. Eventually they may end up here.) NOTE: Please put *Circuits, Schematics and Manuals* in the section with that name.

Hi,
I came across some docs that may be of interest.

First, the Phillips Miller recorder recorded mechanically on film to be read optically. The cutter head was moving iron, of course.

Hey Fela!

THX for sharing - great stuff!
I also don't own that book but always was corious about the Philips design which seems kind of similair to bbc/grampian.
Also interresting to see the "stereo" version which reminds me very much of an Emory Cook approach but some years earlier.
Also I've read some of that stuff in another book in an old library in my town, maybe I have to go there for another research...

Cheers
Lukas

Did they all come from here?

http://www.extra.research.philips.com/hera/people/aarts/_Philips%20Bound%20Archive/PTechReview/

I had been working my way through these some months back, if you go back to the parent directory there may be others under some of the tabs. It took me a bit of searching to find it and to truncate the link to get to the parent directory. I had looked through some of them and had been downloading them for later reference and review.

Enjoy there's a lot of reading in there.

There is bound to be other stuff in there of interest as well about discs and cutting, as well as associated subjects. Now others can go seek and find.......

It is the same, just need to flip back to the parent directory, I got the link in an email months back on another group I think. I thought it might be useful so I started to download some of them for future reference and review of contents at a later date.

Thank You! This one is VERY useful! Nice to see further treatment of the topic, except for the original Buchmann- Meyer article (from which this one seems to be borrowing illustrations).

Bastiaans also appears as an author in the AES disk recording anthology.
