摘要： Respective processes of decoding in error correction are subjected to parallel processing using a plurality of processing elements (PEs) each having the same configuration. At any given time, when processing of one process has been terminated, processing proceeds to a PE having the highest priority among PEs waiting for processing. The PE which has received data recognizes and executes the next process for that data.

摘要： An optical information recording/reproducing apparatus for stably recording, reproducing, or erasing the information by a laser beam with respect to different kinds of optical disks is represented. This apparatus includes a processor to record, reproduce, or erase the information for an optical disk, a disk sort detector to detect the sort of optical disk, and a controller to control the processing parameters of the processor in response to an output signal from the disk sort detector. The disk sort detector reads the disk sort identifying information preliminarily recorded on the optical disk by the processor to detect the sort of disk. Or, this detector irradiates light onto labels having different reflection factors or transmission factors preliminarily provided on the optical disks by the processor and detects the reflected light amounts or transmitted light amounts from the labels, thereby detecting the sort of disk. The optical disks include disks of the type only for use of reproduction, the rerecordable type, and the writable type.

摘要： A multiplier calculates a product S'(x)=S(x).multidot..lambda.(x) mod X.sup.d-1 of a syndrome polynomial S(x) generated by a syndrome generator and an erasure position polynomial .lambda.(x) generated by an erasure position polynomial generator, modulo X.sup.d-1. A constant multiplier sequentially multiplies coefficients of the polynomial S'(x) and the erasure position polynomial .lambda.(x) with a power of a primitive root .alpha. of a code. The power exponents in this multiplication are determined in units of coefficients. Every time this multiplication is executed, an adder sequentially adds predetermined combinations of products. A plurality of arithmetic and logic operations according to the numbers of correctable erasures and errors are sequentially executed using the sums. A divisor and dividend are selected in accordance with the number of erasures included in the code on the basis of the plurality of arithmetic and logic operation results. A division is executed using the selected divisor and dividend. A value at a position, discriminated to be an error position, of the code is corrected based on the division result, thus performing error correction including erasure correction with a simple circuit arrangement.

摘要： In reproduction of information, a decoding program is reproduced from an information recording medium on which information is enciphered and recorded, and an encryption key and the decoding program, which are used to decode the information, are recorded as well. At least one of the encryption key and the decoding program is erased in accordance with an instruction from the decoding program. It is confirmed whether at least one of the encryption key and the decoding program has been erased. Activation of the decoding program is terminated when it is confirmed that at least one of the encryption key and the decoding program has been erased.
