摘要： The method employs an optical disk having V-shaped grooves formed by respective slant faces. First and second laser beams are focused, by an objective lens, into respective spots (1, 2) on the respective adjoining slant faces (C, D) of a groove for recording and reproducing information. A third laser beam is focused, by the same lens into at least one spot (3) on the bottom of the V-shaped groove for concurrently erasing information on the adjoining slant faces (C, D). The disk comprises recording material for enabling recording by heating and fast cooling and erasing by heating and slow cooling.

摘要： An optical disk (10) is disclosed which records information that can be optically read. The disk has a spiral guide track (14). The disk further includes a single index field (20) and a plurality of sectors (18). The index field includes an index mark (22) that indicates the position at which an optical head is caused to jump for repeated trace of a specific portion of the guide track. Each of the sectors has a sector head (26) and a data field (30) that comes following the sector head. The sector head comprises a sector mark (26) located at the head of the sector and an address field (28). This address field contains a track address, a sector address, and an error detecting and correcting code. The index mark in the index field is detected, and the optical head is made to perform a jumping operation in response to the resultirg signal, whereby the jumping operation is rendered certain. When the address fields are being read, if some sector addresses cannot be read due to drop-out or for other cause, tie signal produced by detecting the index marks are counted by a counter into which the signal produced by detecting the sector marks is clocked, for preparing the sector addresses.

摘要： A read only type optical disc, and disc drive apparatus for reading/additionally writing data into the disc. The disc has a recording material (7) formed in all of the tracks (6) by which data can be additionally recorded on the disc (l). This optical disc has a plurality of sectors (S₀ - S n ) forming a data read-only area (4) and a write/read area (3). Each area has track sectors (S₀ - S n ) each having a sector identifier portion (ID) in which address information is recorded and a data field portion (DF) to record data. Datafield identification flags (F₁, F₂) indicative of the read-only area (4) and the write/read area (3) are recorded in the respective identifier portions. On reading or writing this optical disc, the data field identification flag is detected to identify (l6, 26, 28) the kind of related area i.e., read-only area or write/read area. Thus, it is possible to avoid (l8 - 22; 28, 34) erroneous recording of data into the read-only area. Upon reading operation, waveform equalization and binary-clipping level of reproduction signals can be well controlled (26, 37, 39). The gain of the servo loop can be switched (53, 54). The track searching operation can be stably performed (58 - 63). The data reading and data writing into the data write/read area can be improved.

摘要： An information recording and reproducing apparatus records and reproduces information in and from a recording medium (11) including an information recording region divided into a plurality of sectors. In recording and reproducing information in and from the recording medium, each sector includes a sector address part (1) formatted and a data recording part (5) for recording data. A predetermined signal is overwritten in the address of a sector thereby to make reproduction of the address impossible to prevent data from being recorded again by error in the sector containing data, while at the same time protecting the writing in the sectors. in data recording, on the other hand, the address signal from the recording medium (11) is binary-coded at a different level to detect a sector of unstable address reproduction, so that a predetermined signal is overwritten in the address of this sector to make subsequent reproduction of the address impossible, thus permitting recording only in the sectors of stable address reproduction for stable data reproduction. Further, an optical disc (11) having sectors of stable address reproduction alone detects a sector of unstable reproduction at the time of inspection, and overwrites a predetermined signal in the address part (1) of the particular sector to make subsequent reproduction of the address impossible.

摘要： An optical information recording and reproducing apparatus for recording and reproducing information on and from an optical recording disk having an optically detectable guide track divided into a plurality of sectors is disclosed.
When a sector to or from which a data is to be recorded or reproduced is a defective sector or a non-use sector because of updating, the sector must be processed such that it is discriminated in a reproduction cycle. A special pattern signal is recorded on the defective sector or the non-use sector, and if the recorded special pattern signal is detected in the reproduction cycle, that sector is determined as the defective or non-use sector and recording or reproducing on or from that sector is inhibited.摘要翻译： 一种光学信息记录和再现设备，用于在具有可分成多个扇区的光学可检测导轨的光盘上记录和再现信息。 当由于更新而将要记录或再现数据的扇区是缺陷扇区或非使用扇区时，必须对扇区进行处理，以便在再现周期中对其进行区分。 在缺陷扇区或非使用扇区上记录特殊模式信号，并且如果在再现周期中检测到记录的特殊模式信号，则该扇区被确定为有缺陷或不使用扇区，并且记录或再现 该部门被禁止。
