    Abstract: Additional information embedded in content data can be corrected with reduced load to hardware. A predetermined amount of content data entered is temporarily stored in buffer means, and from the content data temporarily stored in the buffer means, additional information embedded in the content is detected. When the additional information detected indicates that the content data can be recorded, the content data is recorded on a predetermined medium, and when the additional information indicates that recording of the content data is inhibited, no recording is performed onto the medium. Moreover, when correction of the additional information is required, the correction is made on the data stored in the buffer means.

    Abstract translation: 本发明旨在能够以较少的硬件负担来修改埋在内容数据中的附加信息。 为此，将预定量的输入内容数据临时存储在缓冲装置中，从临时存储在缓冲装置中的内容数据中检测内容数据中的附加信息，检测到的附加信息的内容被估计， 当估计可以记录内容数据时，内容数据被记录在预定介质中，并且当估计内容数据不被记录时，使内容数据不被记录在介质中。 此外，当估计需要修改附加信息时，存储在缓冲器装置中的相关部分的数据被存储在缓冲器装置中被修改。

    Abstract: A data record medium on which a digital signal has been recorded is disclosed, the digital signal being composed of main data and a sub code, the sub code having time information representing reproduction elapsed time, the sub code being recorded in association with the main data, wherein information that represents the reproduction elapsed time of the sub code is represented with a binary coded decimal number and address information in synchronization with the time information of the main data is represented with a binary number, the address information being contained in the main data.

    Abstract: If there is any portion in channel bit data obtained on converting a signal read out from a recording medium into a bilevel signal which fails to satisfy a condition concerning a minimum run length or a maximum run length of the same symbol, the channel bit data is corrected to improve the bit error rate to secure a skew margin. To this end, channel bit data not satisfying a minimum run length d' of the same symbol is detected by a (d'-1) detector 4 using n-tupled clocks obtained on n-tupling channel clocks of playback data by a bit clock generator 2, where n is an integer not less than 2. A correction position of the channel bit data having the run length of the same symbol equal to (d'-1) is designated by a correction bit position designating unit 5. A data correction unit 6 then corrects the channel bit data so that the minimum run length of the same symbol will be equal to d'.

    Abstract: In a magneto-optical recording apparatus, light spots are successively formed on a magneto-optical disc (2) at a timing of a predetermined reference clock signal (SCK), and record data are magnetically recorded onto the disc (2) by applying a predetermined modulation magnetic field (HM) of which the polarity is inverted depending on the record data in synchronism with the reference clock signal (SCK). At least one of the timing of irradiating a light beam (LA1) forming the light spots, the light volume of the beam or the irradiation time is controlled depending upon the temperature of the disc (2) and/or the scanning position of the light spot, in order to form a pit (P) at a correct position relative to the timing of the reference clock signal (SCK).
