The 44-year-old and her husband Charlie, 49, appeared at Southwark Crown Court, but were bailed again until September 26.
Brooks, the former editor of the News of the World, is facing three counts of alleged conspiracy to pervert the course of justice.
The 44-year-old was charged last month by officers from Operation Weeting, the police investigation into phone hacking by newspapers.
She stands accused of conspiring to conceal documents, computers and electronic equipment from police, as well as allegedly removing seven boxes of material from the archive at News International.
Her racehorse trainer husband, Charlie Brooks, is facing a single charge of conspiring to pervert the course of justice.
Four of Brooks's former colleagues - her previous personal assistant Cheryl Carter; chauffeur Paul Edwards; Mark Hanna, head of security at News International; and security consultant Daryl Jorsling - are also facing a single charge of the same offence.
They have all been bailed to appear at Southwark Crown Court on September 26.
