摘要： In a recording and reproducing apparatus for inputting recording data (S1) into a predetermined recording and reproducing means, outputting as reproducing data (S15), when record assurance is conducted by comparing the recording data with the reproduced data, an error detection code is calculated for the recording data, and the error detection code is compared with the error detection code which is obtained from the reproduced data by a predetermined comparison means (33), thereby allowing the volume of information to be transmitted from the recording system to the comparison means to be considerably reduced. Therefore, the capacity of the delay memory (32) for delaying the error detection code which is calculated from the recording data for the portion of the processing time in the recording and reproducing means can be considerably reduced.
摘要翻译： 在将记录数据输入预定的记录和再现装置的记录和再现装置中，作为再现数据输出，当通过将记录数据与再现的数据进行比较来进行记录确认时，计算记录数据的检错码， 将误差检测码与由预定比较装置从再现数据获得的检错码进行比较，从而允许从记录系统向比较装置发送的信息量大大减少。 因此，可以显着地减少用于延迟从记录和再现装置中的处理时间部分的记录数据计算的错误检测码的延迟存储器的容量。
