Re-mastered LP question

I have recently purchased the RCA Hefitez Box Set from Classic Records. One of the records is the Beethoven Violin Concerto (LSC 1992), which I also have the original 1963 pressing. What puzzles me is that the music grooves on the 1963 pressing covered the entire surface of both sides but the newly re-mastered one only covered about 2/3 of the surfaces.

Does anyone have a good explanation for this?

Not sure about that particular LP, but some of the older LPs like that had wider groove spacing to allow for more dynamics. It is possible that the remaster had some compression applied to allow for closer groove spacing. This was quite common in the Dynagroove series.

Although what Twl says is generally true, that (compression) is clearly not the case with the Classic reissue, which is superior in terms of dynamics and resolution of ambient detail than (though not as warm as) the original issue, as we found in a comparison in my system. I'm curious as to why the grooves are closer together myself; perhaps an inquiry of Mike Hobson might give an answer.

Perhaps the cutter lathe technology has improved allowing the grooves to be placed closer together.
