...yet another option ("file" would also work).

For example: "The reality of the record, however, establishes that it was the State which made Ms. Cardona's relationship with Gonzalez a central theme of its case, because it needed to convince the jury that it was Ms. Cardona, and not Gonzalez, who was the primary abuser of Lazaro and thus responsible for his murder." (See page 11 here: http://www.wfsu.org/gavel2gavel/briefs/01-1056_replytorespon... .)

Black's Law Dictionary (8th ed.) has this to say:
record, n. [...] 3. MINUTES (2). 4. The official report of the proceedings in a case, including the filed papers, a verbatim transcript of the trial or hearings (if any), and tangible exhibits. —Also termed (in some jurisdictions) clerk's record; (in BrE) bundle. See DOCKET (1).

file, n. 1. A court's complete and official record of a case[, e.g., "]the associate went to the courthouse to verify that the motion is in the file["]. 2. A lawyer's complete record of a case[, e.g., "]the paralegal stored the file in three drawers in her office["].

Here are some more examples used in court decisions:

"Plaintiff’s post-trial insistence that such a request was made does not square with the reality of the record, or with its stance over the course of this trial." (See page 10 here: http://www.ctd.uscourts.gov/Opinions/060801.JBA.Travel.pdf .)

"The majority has succumbed to engaging in pure speculation rather than accepting the reality of the record before us." (See the end of page 63 here: http://www.aoc.state.nc.us/www/public/sc/opinions/2009/pdf/5... .)
