摘要： The present invention discloses an optical disk formed according to double injection molding of forming an area of the optical disk on which a recording film is formed, namely, an outer circumferential area by using polycarbonate that is an amorphous polymer, and forming an area of the optical disk on which the recording film is not formed, namely, an inner circumferential area by using a semi-crystalline polymer having a similar elastic modulus to that of polycarbonate and having durability to a static fatigue, especially polyamide. Therefore, the optical disk is efficiently prevented from being damaged by restricting growth of cracks near its hole, obtaining excellent optical characteristics as an information recording medium.

摘要： Disclosed is a method of preventing optical recording media from being fractured and apparatus thereof, which enable to prevent an optical disc of an optical disc drive from being fractured due to a crack. The method and apparatus comprise: detecting a first tracking error signal outputted from a data recording/reproducing apparatus when the optical recording media are rotated at a first speed; detecting a second tracking error signal outputted from the data recording/reproducing apparatus when the optical recording media are rotated at a second speed; determining whether or not the crack on the optical disc exists on the basis of the first tracking error signal and the second tracking error signal; and stopping an operation of the data recording/reproducing apparatus when the optical recording media have the crack.

摘要： An optical disc drive include a turntable for mounting an optical disc, a driving unit rotating the turntable, and an optical disc heating member for heating a center portion of the optical disc. In the optical disc drive, an inner circumference temperature of the optical disc is maintained to be higher than a peripheral temperature of the optical disc by at least 50° C. According to this, a growth of a crack generated at a periphery of a hole of the optical disc is restrained thereby to effectively prevent a damage of the optical disc.
