摘要： A method for recording digital data on a tape in such a manner that the recorded data will not cause misoperations of the reproducing apparatus due to an excessive error rate. A flag in received data is monitored. When the flag indicates that a block of data contains more errors than can be corrected in the reproducing apparatus upon reproduction, the data block is either replaced by null data or a previously received data block having an acceptable error rate, the choice being in accordance with an input mode instruction.

摘要： An information record medium (1: DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80), and performs a reproduction while moving the read device along the record track at a predetermined reading linear velocity. The record information is divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by the information reproducing apparatus, recorded on the record track. Lowest reading rate information (212) indicates a minimum requirement of a reading rate for the information reproducing apparatus to reproduce a reproduction unit, which comprises at least one of the first data groups and which is to be reproduced by the information reproducing apparatus such that a sequential logical meaning of the reproduction unit is continuous. The lowest reading rate information is recorded on the record track at one portion (LI, 11, 41) different from another portion where the record information is recorded.
