Hello, does anybody know when hard disk recorders came along, instead of tape? I'm just looking for technological advancements in these periods. My understanding is that in the 1970's, 24 track anolog consoles were available, along with 2" tape. I know that in the late 80's new technology came along which made big differences, but I'm not sure about any of it, nor can I find information regarding any of it. Does anybody know?
