Abstract
When recording digital data on a recording medium, digital data is divided into information units of digital data which are further divided into recording units to be recorded on the recording medium. The digital data is recorded in the recording medium together with identification information to specify the information unit of the recording unit. When reproducing, the digital data which has been reproduced from the recording medium is temporarily stored in a memory unit whose capacity is more than one information unit. After the stored digital data reaches a capacity of at least one information unit or more, the digital data is outputted from the memory unit in the information unit format. Furthermore, when the reproducing operation is discontinued, a controller stored the identification information of the recording unit to be reproduced next, and the digital data of the recording unit to be recorded next is subsequently reproduced on the basis of the identification information when re-starting the reproduction and is stored in the memory unit, thereby causing the reproducing operation to become more reliable.
