Abstract: A plasma processing apparatus in which power consumption is reduced, which can generate uniform plasma in a large range and in which minute processing in high etching selectivity and in high aspect ratio is enabled is disclosed. High density plasma is generated in a vacuum vessel housing a processed sample utilizing an electron cyclotron resonance phenomenon caused by an electromagnetic wave in an ultra-high frequency band and a magnetic field and the surface of the processed sample is etched using this plasma. An electromagnetic wave in an ultra-high frequency band for generating plasma is radiated from a planar conductive plate consisting of graphite or silicon which is arranged opposite to the surface of the processed sample into space inside the vacuum vessel. High density plasma in the low degree of dissociation can be generated by using an electromagnetic wave in an ultra-high frequency band and as a result, the controllability of etching reaction can be enhanced.

Abstract: In a compression data editing apparatus, a smooth switching (edition) having no noise is enabled to be performed. A code train 10 is supplied to an MPEG decoding circuit 2 and is delayed by a fixed time and, after that, it is decoded into an audio signal. In this instance, the operation is temporarily stopped for a block which is repeated. When an offset value extracted by an offset extracting circuit 3 lies within a predetermined range, the repeat pulse is detected and supplied to the circuit 2. A flag is set to a frame in which the pulse is detected. In the circuit 2, the decoding is temporarily stopped in the code block which corresponds to the pulse and was recorded at the second time. The decoding is restarted after the next block was inputted. In the circuit 2, the supplied code train 10 is supplied to, for example, a synthesis filter of 512 taps and is converted into the audio signal.

Abstract: A data recording/reproducing method for a non-rewritable recording medium of a rotating type, each of tracks on the recording medium is divided into a plurality of blocks which are allotted with respective addresses. Each block includes a data recording area and a deletion flag area which is divided into a plurality of sub-areas. One of the sub-areas in a given block is associated with other block which is in a predetermined address relation with the given block. When the content in the data recording area of one block on the recording medium is to be rendered invalid, deletion flag information is also recorded in the sub-area of the other block having the predetermined address relation with the one block. Upon reading, the data of the blocks read out from the recording medium exclusive of the data of the block determined to be invalid on the basis of the flag information is transferred to a high-rank system.

Abstract: An information recording method and system for writing information onto a recording medium. If an error area is detected in a check of the information read out of the medium after writing, the information is rewritten onto an alternative area on the recording medium using a buffer memory while the information in the error area is kept valid. Loss time accessing the alternative area is eliminated until the error checking and correction in the error checking and correction circuit is not available for the information read out of the error area through a reading circuit.

Abstract: A tape drive control apparatus and method for a magnetic tape recording and reproducing system are provided to prevent a failure of the read and write operations due to frequent start and stop actions of the magnetic tape. The magnetic tape has a certain resonance frequency between a read/write magnetic head and a tape guide of the system. When the rate of start and stop actions of the tape approaches the resonance frequency adverse vibration of the tape becomes large in magnitude. To prevent such tape vibration delay a delay circuit is provided to delay the start of the magnetic tape for the subsequent data block when the length of the preceding data block is within a predetermined range.
