Hitachi has announced the formal unveiling of the word’s first Blu-ray (BDs) camcorders. The DZ-BD70 is a single drive cam that can record approximately an hour of 1920 x 1080 of full high-def video (two hours of 1440 x 1080) on an a single side, single layer 8 cm BD. The DZ-BD7H (shown here) is a hybrid with a 30 GB built-in HDD which can record up to four hours of 1920 x 1080 high-def video (4 hours of 1440 x 1080) and can also copy its contents from HDD to BD within the camera itself. Both models will be available in Japan at the end of August and will come across the seas in October, just in time for the Christmas Disc War to heat up.
