Multichannel digital-signal reproducing apparatus for switching access timing relative to reproducing timing based on a determination of recorded/reproduced information
摘要：
An apparatus for reproducing digital information from a recording medium having a plurality of parallel tracks and digital information recorded thereon as n-channel (n being an integer greater than or equal to 2) digital signals. The n-channel digital signals are reproduced by n-reproducing heads. The digital information contained in the reproduced signals is stored in a storage device. Discriminating data is obtained for determining which of the n-channel digital signals reproduced correspond to the reproducing heads. The timing of an access device, accessing the storage device for performing a predetermined processing of the digital signals stored in the storage device relative to the reproducing timing of the digital information reproduced by the n reproducing heads, is controlled in accordance with the discrimination data.
摘要（中）：

一种用于从具有多个并行轨道和其上记录的数字信息的记录介质再现数字信息的装置，其中n信道（n是大于或等于2的整数）数字信号。 n路数字信号由n个再现头再现。 包含在再现信号中的数字信息被存储在存储装置中。 获得鉴别数据，用于确定所再现的n路数字信号中的哪一个对应于再现头。 根据鉴别数据控制存取装置的访问存储装置，用于对存储在存储装置中的数字信号进行预定处理，相对于由n个再现头再现的数字信息的再现定时。
