Another investigation, Case 3000, centers on potential misdealings in a multi-billion shekel deal to purchase naval vessels from Germany.
Case 2,000 relates to claims of a proposed deal for more favorable coverage with Arnon Mozes, the publisher the Yedioth Ahronoth newspaper.
Police have issued a gag order as they try to persuade Netanyahu's former chief of staff Ari Harow to be a state witness in the cases.
Israeli police revealed last week that Netanyahu is suspected of crimes involving fraud, breach of trust and bribes.
According to the ruling, the prime minister will also need to disclose the dates of phone conversations with the editor-in-chief of the paper, which is widely regarded as strongly pro-Netanyahu in its orientation.
Netanyahu, 67, is a suspect in two cases. Germany postponed the submarine deal due to the investigation.
Adelson, a casino magnate, and his wife during recent visits to Israel have been questioned twice by police investigators in corruption scandals that allegedly involve Netanyahu.
If Harow gives evidence against his former boss, it would increase the chances of Netanyahu facing charges. An indictment, which could still be months off, does not necessarily mean Netanyahu will step down, according to analysts and those familiar with Israeli law.
After eight years in office, in addition to an earlier term in the 1990s, Netanyahu has garnered an image as a cigar-puffing, cognac-drinking socialite who is as comfortable rubbing shoulders with global celebrities as he is making deals in parliament.
Police have been questioning Netanyahu for months over the cases, but have released few details. Olmert was forced from power in 2008, leading to early elections in 2009, when Netanyahu was elected to the premiership.
Netanyahu has repeatedly denied wrongdoing and calls the accusations a witch hunt.
Netanyahu said that he "does not comment on background noise, and is continuing to work on behalf of Israelis".
Netanyahu must transfer the call log to Channel 10 and Drucker within 15 days. Baklava is his achilles heel.
