    • Provided is a communication device capable of extending a power supply unit to a second casing without the need for additional components. A mobile telephone (1) comprises a circuit board (70) disposed at an operation unit-side casing (2), a circuit board (80) disposed at a display unit-side casing (3), a circuit part formed on the circuit board (70) and having a ground pattern and a contact point (104), a reference potential pattern layer (75) disposed at the operation unit-side casing (2) and electrically connected to the ground pattern, a reference potential pattern layer (86) disposed at the display unit-side casing (3), and an FPC unit (101) for electrically connecting the circuit board (70) with the circuit board (80). The FPC unit (101) comprises a signal line (210) for transmitting a predetermined signal and a shield layer (240) for electrically shielding the signal line (210). The shielding layer (240) is electrically connected to the contact point (104) in the operation unit-side casing (2) and is thus electrically connected to the reference potential pattern layer (86) in the display unit-side casing (3).
    • 提供了能够将电源单元延伸到第二壳体而不需要附加组件的通信设备。 移动电话(1)包括设置在操作单元侧壳体(2)的电路板(70),设置在显示单元侧壳体(3)的电路板(80),形成在电路 板(70)并具有接地图案和接触点(104),设置在操作单元侧壳体(2)处并电连接到接地图案的参考电位图案层(75),参考电位图案层 86)设置在显示单元侧壳体(3)上,FPC单元(101)用于将电路板(70)与电路板(80)电连接。 FPC单元(101)包括用于传输预定信号的信号线(210)和用于电屏蔽信号线(210)的屏蔽层(240)。 屏蔽层(240)电连接到操作单元侧壳体(2)中的接触点(104),从而电连接到显示单元侧壳体(3)中的参考电位图案层(86) 。

    • An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors. independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device. Each of the zones can be set to serve as any of the different types of recording area, independently of other zones.
    • 光盘物理上具有划分成区域的记录区域,每个区域包括彼此相邻的物理轨道。 在每个物理轨道中提供整数个扇区。 在更向外的区域中角度记录密度较高,使得整个记录区域的线性记录密度基本恒定,并且逻辑磁道由预定数量的扇区形成。 独立于物理轨道。 从磁盘读取的逻辑磁道和扇区地址与从主机设备提供的线性逻辑地址之间的转换很容易。 写入数据实际记录的逻辑磁道中的扇区头部的地址,包括用于代替缺陷扇区的替代扇区,优选地是连续的,以进一步促进从盘读取的逻辑磁道和扇区地址之间的转换 从主机设备提供的线性逻辑地址。 每个区域可以设置为独立于其他区域,用作任何不同类型的记录区域。
