    2-1 Overview The DZ-BD7HA and DZ-BD70A can record High-Defi nition (HD) images on a Blu-ray disc (BD). The DZ-BD7HA also has a 30 GB HDD (1.8-inch), and so it can record high-defi nition (HD) images on the HDD. Since the DZ-BD7HA and DZ-BD70A are compatible with various discs, as shown in Table 2-1-1, it can record movies directly to a disc or the HDD, and also easily dub movies recorded on the HDD to a disc (dubbing from a disc to HDD is not possible).
