Except for the old IVC-9000, long obsolete, no tape recorder will
accept direct RGB analog component signals. For high quality
single-frame work, I use a Betacam BVW-75  editing recorder which
accepts Y, R-Y, B-Y (another type of three component video signal).

I use a transcoder to convert RGB to Y, R-Y, B-Y. The "Y" is for luminance,
the other signals are algebraic color difference signals similar to the "I"
and "Q" of NTSC or the "U" and "V" of PAL composite video.

This is expensive, though.  US$ 50K for the Betacam, US$ 5K for the xcoder,
another US$ 5K for a dedicated animation controller to step the VTR through 
the series of single frame insert edits required for animation recording...

What you might consider is a recordable videodisk unit from SONY, the 
LVR-5000, which records RGB directly in 525- (NTSC) or 625- (PAL) line 
format. It is stepped though an ASCII command to an RS-232 port on the unit.
Price is about US$ 18K for the unit, I don't know about the disks.

Cheaper systems are available with lesser quality.
