    摘要： An optical disk of the present invention has one or more recording tracks formed concentrically or spirally on the disk to which data signals are recorded by forming different-length marks and spaces on the tracks. An ID signal combining marks and spaces of two or more predetermined lengths approximately equal to the length of the marks and spaces forming the data signals is recorded to the recording tracks within a predetermined disk area, thus creating the ID signal by aligning the marks and spaces in the radial direction and recording the aligned marks and spaces to adjacent tracks in a predetermined radial disk area. Also, a reproduction apparatus for reproducing signals from the optical disk is disclosed.

    摘要： In an optical disc, an ID field contains a plurality of address information, and is preliminarily recorded in convex and concave signals, and is composed of two sets offset by about ½ track pitch toward the internal or external track direction adjacent to the guide track, an information recording field is composed of grooves and lands oscillating at a single frequency in the radial direction, and the grooves and lands alternate in every revolution of the guide track. When w bits of information are included in one period of oscillation, an information unrecorded field between the ID field and information recording field is arranged to have a length of w/10 bits or more and/or w bits or less, and therefore, when recording continuous information data such as video data, it is possible to record continuously by generating a clock securely from the oscillating signal, and moreover, the format efficiency is improved, so that a format of a larger capacity is achieved.

    摘要翻译： 在光盘中，ID字段包含多个地址信息，并且预先记录在凸和凹信号中，并且由邻近导轨的内部或外部轨道方向偏移大约1/2道距的两组组成， 信息记录区域由在径向上以单个频率振荡的凹槽和平台组成，并且凹槽和平台在导轨的每转一圈中交替。 当信息的w位被包括在一个振荡周期中时，ID字段和信息记录字段之间的信息未记录字段被布置为具有w / 10位或更多个和/或w位或更少的长度，因此，当 记录诸如视频数据的连续信息数据，可以通过从振荡信号安全地产生时钟来连续记录，此外，提高格式效率，从而实现更大容量的格式。
