  • Thin film magnetic head and magnetic recording apparatus
    Publication number: 20060221499
    Abstract: The present invention provides a thin film magnetic head realizing the gradient and the strength of a perpendicular magnetic field increased as much as possible. A main magnetic pole layer is made recede from a write shield layer. As compared with the case where the magnetic pole layer is not receded from the write shield layer, an overlap range in which the main magnetic pole layer and the write shield layer are overlapped one another is smaller. Accordingly, the amount of magnetic flux emitted from the main magnetic pole layer toward a recording medium relatively increases, and the amount of magnetic flux leaked from the main magnetic pole layer to the write shield layer relatively decreases.

  • Optical disc for storing moving pictures with text information and apparatus using the disc
    Publication number: 20060159431
    Abstract: When moving pictures are recorded onto an optical disc, not only is text data recorded, but also video-recording start date and time, video-recording end date and time, and source name or channel number serving as primary text data are recorded in alphanumeric characters program by program or cell by cell, a program or a cell being used as a unit of video-recording. Other text data is recorded together with language code. Since the primary text data used to select video data is expressed in alphanumeric characters, a program or cell to be reproduced can be selected, regardless of language, and the text information in the same language as that of the apparatus can be searched for.

  • Digital video system
    Patent number: 7079754
    Abstract: The erasion level appending range of a file is instructed. According to this instruction, the erasion level is set. When this setting range does not agree with the cell unit of the current cell, the current cell is divided to set a sequence of divided cells. Playback management information of each of the divided cells and current cell is re-created, and erasion level information is appended to playback management information of the divided cell that belongs to the appending range.
