High density disc

High density disc

A high density disc having a data area (130) which is set to maintain compatibility with existing drives while providing a superior recording/reproducing feature. The high density disc has a center hole (100), a clamping area (110), a data area (130) where user data is recorded, a lead-in area (120)...

description A high density disc having a data area (130) which is set to maintain compatibility with existing drives while providing a superior recording/reproducing feature. The high density disc has a center hole (100), a clamping area (110), a data area (130) where user data is recorded, a lead-in area (120) located at the inner side of the data area, and a lead-out area (140) located at the outer side of the data area. In the high density disc the diameter of the center hole (100) is 10 mm or more, and the inner diameter of the clamping area (110) is characteristically within a range of 20-26 mm. Also, the inner diameter of the data area (130) is characteristically within a range of 35-40 mm. Therefore, while a conventional disc drive is still used, the size of the high density disc decreases and a recording capacity can be increased.
