Using compression to saturate cassette tape

[WHR]

I have a Marantz Professoinal Cassette recorder. When the meters touch the red it clips, even when using Chrome masters. I once watched a professional live sound engineer record live onto the same deck, and using compression he was able to record well into the red. It saturated the tape with a beautiful clean sound with virtually no noise. Can anyone tell me the process for doing this using my home studio to make vocal speach masters.

I usually just saturate the tape with the level if that's what I'm wanting to do. I've never used compression on a final stereo mix.
I use it while tracking.

Just a head's up for ya. That tape you are using, if it is Chrome/METAL will wear your heads faster if used on a regular basis than Cr02 Hi-Bias.

You didn't say that it was metal tape, but I thought I'd throw that in for ya anyway.
