In Article I, Section 5 of the United States Constitution, it states, "Each House shall keep a Journal of its Proceedings, and from time-to-time publish the same, excepting such Parts as may in their Judgment require Secrecy;...". Accordingly, the Journal and not the Congressional Record, is the official record of the proceedings of the Senate.
The Journal is the official record of proceedings of each legislative day in the Senate. The Journal records the result of every vote, and state in general terms the subject of it. The Journal contains no verbatim debate, but instead a rendition of all the official actions of the Senate, including every motion made and every vote taken.
