Abstract
Data decoding decodes data reproduced from a record medium and stored in a memory. Since decoding requires a sufficient amount of data to be stored in memory especially when the data is, for example, predictively encoded, a system controller is provided which inhibits previously read data from being overwritten in memory. Thus, when a reverse reproduction operation is suddenly initiated during a forward reproduction operation, a sufficient amount of data is reserved in the memory for decoding the data in the reverse direction. Similarly, the system controller inhibits the memory from writing over previously read data during a reverse reproduction and a sufficient amount of data is reserved for decoding when forward reproduction is resumed.
