摘要： A magnetooptic recorder player provides for residual data checking and media defect checking. Media defect checking is effected by comparing the reflected light intensity of a modulated optical beam with the input data characteristics. A difference between the input data and the detected light intensities represents asperities in the record media. Residual data is checked by selectively gating MO detected signals during recording, which are intermediate the high intensity light beam pulses used for recording signals. Both the detected residual data and detected media asperities are counted for each addressable record storage area on the medium.

摘要： Rewriteable media, such as magnetooptic record members or disk has its recording controlled such that the recording is certifiable as meeting write once read many characteristics. Controls are introduced for the entire disk for indicating that the rewriteable disk is to be used for certified or vault writing, at least in some radial zones of the disk. Recording or writing operations are limited to those addresssable areas on the certifiable rewriteable medium that have not been previously written. Each of the addressable areas of the medium, in a disk termed, sectors, have a precursor portion called a control area which indicates the status of the sector and is used for preventing overwriting or erasure as well as controlling.

摘要： A control system for dynamically regulating an operating condition of a device used with and controlled by a host computer system. The inventive system includes a sensor arrangement for detecting the desired operating condition of the device and providing a signal in response thereto. A control system dynamically regulates the operation of the device in response to commands generated by the host system and the sensor output signal to maintain the operating condition of the device within predetermined parameters. In a particular implementation, the advantageous teachings of the present invention are incorporated in an optical drive system. One or more sensors are used to detect the operating temperature of the drive and provide an analog output signal in response thereto. The signal is digitized and input to a microprocessor based control circuit. When the temperature of the drive exceeds a first threshold, the control circuit dynamically adjusts the duty cycle of the drive by inhibiting high temperature write and erase operations. When the temperature of the drive exceeds a second threshold, the control circuit inhibits the lower temperature read and verify operations as well. As a result, the controller maintains the operating temperature of the drive within predetermined parameters which may be controlled by the user through the host computer.

摘要： A data recorder, preferably of the magnetooptic type, employs a rotating record storage disk. The record storage disk has a track starting primary data storing sector circumferentially adjacent to the track starting sector or a small plurality of alternate data storing sectors which are not addressable directly by mechanisms outside of the recorder as are the primary recording sectors. Whenever a one of the primary sectors in a given track is found to be defective, then one of the alternate sectors in that same track receives data from a one of the primary storing records of sectors in the same track. A small number of alternate sectors are selected to extend circumferentially for creating an elapsed scan time over the element of sectors not less than the elapsed time required for the recorder to switch from scanning one track to scanning an adjacent one of the tracks. In a magnetooptic recorder, the elapsed time selected for scanning the small plurality of alternate sectors is also not less than the time to reverse the magnetic biasing field for erasing and recording on the disk. Alternate sectors provide both for alternate data storage and for the preparatory steps of track jumping or switching and magnetic field bias reversal. Second alternate ones of the tracks are selected in the event all of the alternate sectors in a given track are filled with data from defective ones of the primary sectors in the same track as the alternate sectors.

摘要： A large capacity data storing disk includes a volume table of contents (VTOC) which identifies allocated ones of data storage tracks and identification of the data contents therein, indications of unallocated data storage track and an indication of which of the data storage tracks on the large capacity disk surface are unformatted. The indications may also include indications of unallocated "erased" tracks that do not contain data residuals from previous recordings. Those unallocated tracks having such erased condition in a count key data record format (CKD) require a home address record on each of the formatted tracks. The home address record may include indications of rotational position of defects to be skipped over during the recording and readback operations. A specific embodiment of the invention using a magnetooptic record medium is described.

摘要： In an optical disk drive, upon each power on or disk receipt, a mode control is set to non-operate, i.e., no commands can be received unless a mode setting command has been received. All other commands are rejected for preventing any access to an optical disk present in the drive until after a mode setting command has been received. When a mode set command is received after a power on or after each disk receipt, the mode control is set to operate which allows receipt and execution of legal commands. The mode setting requirement forces selection of write verify or not and to turn laser off or not after a predetermined time delay after completing a last command.
摘要翻译：在光盘驱动器中，在每次上电或磁盘接收时，模式控制被设置为不操作，即除非已经接收到模式设置命令，否则不能接收命令。在接收到模式设置命令之前，所有其他命令都被拒绝，以防止访问驱动器中存在的光盘。在接通电源或每次接收磁盘之后接收到模式设置命令时，模式控制被设置为允许接收和执行合法命令的操作。在完成最后一个命令之后，模式设置要求强制选择写入验证并在预定的时间延迟之后关闭激光器。

摘要： An apparatus and method are provided for tracking the number of permanent and temporary errors, and spare sectors used as a result of the errors, on a per disk and per drive basis. During read/write operations, a determination is made as to whether the number of spares used to replace defective sectors on a disk, together with the number of spares used to replace defective sectors during formatting, exceeds a predetermined limit. This limit can be different depending upon the type of disk in use, rewritable or WORM. If the limit is exceeded, diagnostics are executed to ascertain the cause of the excess usage and appropriate corrective action, such as requesting that the disk and drive lens be cleaned, is initiated. Moreovers, an attempt can be made to recover used spare sectors on a rewritable disk.

摘要： A data file having a plurality of data blocks is divided into one or more transfer units of data blocks. Before data storage, each transfer unit of data blocks is subjected to its own data compression cycle to create a group of compressed data blocks. The size of the data transfer unit, in bytes, is selected to facilitate addressing and retrieving individual recorded groups of compressed data blocks while providing good channel utilization and compression efficiency. Also the data transfer unit size is selected in part based upon data storage efficiency, i.e. the storage of the compressed data should fill as many addressable data storage areas as possible. Upon recording each group of compressed data bytes, an entry is made into a file directory for enabling addressing the recorded compressed data blocks.
摘要翻译：具有多个数据块的数据文件被分成数据块的一个或多个传送单元。在数据存储之前，数据块的每个传送单元经受其自己的数据压缩周期以创建一组压缩数据块。选择数据传输单元的大小（以字节为单位），以便于在提供良好的信道利用率和压缩效率的同时寻址和检索各个记录的压缩数据块组。此外，数据传输单元大小部分地基于数据存储效率来选择，即压缩数据的存储应尽可能地填充尽可能多的可寻址数据存储区域。在记录每组压缩数据字节时，将条目作为文件目录，以便对所记录的压缩数据块进行寻址。
