摘要： Provided is a small form factor optical/magnetic disk including an integrated metal hub and a disk plate. The integrated metal hub includes a circular upper metal hub and a circular lower metal hub integrally formed with and disposed under the upper metal hub. The circular lower metal hub has a smaller diameter smaller than the upper metal hub. A central hole is formed in central portions of the upper and lower metal hubs and passes through the upper and lower metal hubs. The disk plate has a through-hole that is formed in a central portion and is directly associated with the integrated metal hub, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein. Since the central portion of the small form factor optical/magnetic disk is not thick, the small form factor optical/magnetic disk can contribute to an ultra thin small form factor information storage device. Also, since manufacturing processes are simple, price and quality competitiveness can be enhanced.
摘要翻译：提供了包括集成金属毂和盘片的小型光学/磁盘。集成金属毂包括圆形上金属毂和与上金属毂一体形成并设置在其下的圆形下金属毂。圆形下部金属毂具有比上部金属毂更小的直径。中心孔形成在上下金属轮毂的中心部分，并通过上下金属轮毂。盘片具有形成在中心部分并且与集成金属毂直接相关联的通孔，以及形成在通孔周围并允许上金属毂安装在其中的凹部。由于小型光学/磁盘的中心部分不厚，因此小型光学/磁盘可以有助于超薄型小尺寸信息存储装置。此外，由于制造工艺简单，因此可以提高价格和质量竞争力。

摘要： Provided is an apparatus and method of initializing a recording layer used in manufacturing a phase-change optical disk for storing information. The optical disk is initialized using a UV lamp in order to initialize the recording layer of the phase-change optical disk capable of repeatedly writing information, without a separate optical head, whereby it is possible to increase productivity by remarkably reducing an initialization time of the optical disk since a large area is initialized using a UV beam.
