Herbie Hancock's Maiden Voyage?

I just bought a copy at a used record store and it's numbered ST 46339. On the back cover it's dated 1997 and say's it's manufactured by Capitol. In the dead wax it says "Mastered by Capitol". Feels like 180g vinyl.
My friend says it's a digital master. I think it's analog. It sounds good to me so it really doesn't matter. I just want to know who's right me or my friend! Hopefully someone here knows.
I tried to google it but can't really find any info on this record.
