ATHENS, April 13 (Xinhua) -- A deep-sea robot craft on Friday located the data recorder on the bridge of the sunken cruise ship "Sea Diamond."

    Experts say the data in the black box will shed ample light on the causes of the accident and will be turned over the investigating authorities as evidence.

    Most of the passengers were safely evacuated after the ship hit the rock on April 5 near the Aegean island of Santorini but two French tourists are still missing.

    According to the ministry of Merchant Marine, the data will be analyzed in detail by specialized technicians, the insurance companies, the Greek coast guard and the ship owners.

    Efforts have begun to recover the data recorder using the two robot craft supplied by the Greek Centre for Marine Research, which are equipped with electronic arms and will attempt to enter the ship's interior. If the robot craft fail because of the way that the sunken ship is positioned, the effort will continue using specially trained deep-sea divers.

    Meanwhile, the Naxos public prosecutor in charge of the investigation into the shipwreck has asked to be given access to the records for the mobile phones owned by captain of the "Sea Diamond" and representatives of the shipping firm that spoke with him around the time of the accident.

    The ship's captain and five other crew members have been charged with negligence, but have not been taken into custody, and are due to give additional testimony next week.
