Abstract:
A data recording apparatus for recording compressed moving picture data on a recording medium, comprising:data storage means for transiently storing moving picture data to be written in said recording medium; retry means for re-writing data corrupted with a writing error on said recording medium if such writing error has been produced during the recording operation; and switching means for switching the operation of said retry means depending on the state of said data storage means at the time of production of said writing error, wherein said switching means compares the free space of said data storage means at the time of occurrence of a writing error to an amount of data stored in said data storage means during the time moving picture data of a data volume written at a time on said recording medium is written on said recording medium; if the free space of the data storage means at the time of occurrence of the writing error exceeds the amount of data stored in said data storage means during the time moving picture data of a data volume written at a time on said recording medium is written on said recording medium, said retry means is operated; and wherein if the free space of the data storage means at the time of occurrence of the writing error is lesser than the amount of data stored in said data storage means during the time moving picture data of a data volume written at a time on said recording medium is written on said recording medium, switching is made to not performing the retry operation.
