摘要： A method of managing a defect of a hard disk drive includes calculating a number of ECC symbols of every sector which becomes an object of a defect scan and setting a defect reference value based on results of the calculation. The hard disk drive sets a sector as a defect sector having the number of ECC symbols greater than a set defect reference value.

摘要： In an iterative error correction method and apparatus for correcting errors in digital data read from a storage medium, re-reads are combined with the error correction procedure in a single error recovery procedure. The data read from the storage medium are represented as a multi-dimensional data structure, and the error recovery procedure is undertaken for each dimension of the data structure. In each dimension, an erasure map is generated that contains errors in the initial read of the data for that dimension, and the errors in the erasure map are deducted as they are corrected in subsequent re-reads. After a predetermined number of re-reads, or when no further errors exist, the error recovery procedure is ended.

摘要： A data storage medium may have data stored on one physical portion of the medium and error correction and recovery data stored on a second physical portion of the medium. In one embodiment, a write once, read many medium may be written with data and the remaining capacity of the medium may be filled with error correction and recovery data. If a portion of the main data is corrupted, the error correction and recovery data may be used to recreate the corrupted data. The error correction and recovery data may be created to fill the unused capacity of the medium by prioritizing and selectively backing up the data when the data use more than half of the medium's capacity, or may create one or more redundant copies of the data if the data consume less than half of the medium's capacity, for example.

摘要： When receiving the reproduced data from the optical disc and buffering same, the buffering from the correct position can be started on the basis of the synchronous signal and the address information included in the sub data which was received simultaneously.There is provided a method for controlling the buffering of the main data which is reproduced from the optical disc, in which the main data and the sub data are received with taking word clocks which are partitioning timings having plural bits of the main data as a unit as references, a synchronous signal which is in synchronization with the main data is generated, and the buffering of the main data is started on the basis of the synchronous signal.

摘要： The present invention relates to a recording medium cartridge memory and recording/reproducing apparatus. A recording medium cartridge consists of a recording medium and a cartridge memory in which a unique ID of the apparatus used for recording/reproducing the cartridge memory is recorded in an unrewritable condition. The apparatus for recording/reproducing the recording cartridge memory consists of a sending/receiving unit which reads out an ID recorded in the cartridge memory, an ID inspection unit inspecting whether or not the ID recorded in the cartridge memory and an ID stored in the apparatus accord by comparing both, and a control unit which records data in a recording medium or control operations of a recording/reproducing unit which reproduces data from the recording medium based on an inspection result in the ID inspection unit.
