摘要： The present invention provides a finalization method and apparatus which enables out a reproduction of an optical disk such as a DVD-RAM by using a reproduction apparatus which carries out CLV reproduction. The finalization method according to the present invention includes creating an unrecorded area map of an optical disk on the Logical block address (LBA). In order to execute in the host application a conversion from LBA to Physical Block Address (PBA) which is normally executed in an optical disk drive, a conversion table from LBA to PBA is created. According to this conversion table, the unrecorded area map is converted from LBA into PBA so as to assure the area to be finalized. A dummy data is recorded in the aforementioned assured area of the optical disk.

摘要： An optical dick, an apparatus and a method for recording/reproducing the optical disk use Gray coded address information. The hexadecimal data 0 to F correspond to the Gray codes. The Gray code consists of the upper address and the lower address. The four channels of the upper address and the four channels of the lower address are set so that one channel of each address is "1". With the change of the data from 0 to F, the channel of "1" in the lower address sequentially moves to the adjacent channel in the corresponding Gray code. Consequently, rapid seeking can be performed by detecting only the lower address.

When a first and second conductivity-type regions are formed on a semiconductor substrate which is selectively irradiated by impurity ions, an excellent super junction is formed by controlling the ion acceleration energy and the width of each irradiated region so that the first and second conductivity-type regions may have a uniform impurity distribution and a uniform width along the direction of irradiation. Another method of manufacturing a low power dissipation semiconductor power device having an excellent super junction is provided which selectively irradiates a collimated neutron beam onto a P+ silicon ingot and forms an N+ region that has a uniform impurity distribution and a uniform width along the direction of irradiation in the P+ silicon ingot.
