Abstract

PURPOSE:To reduce missing of reproducing data due to displacement or media deformation, by controlling data processing of return path, based on readout data of a moving head at outgoing path. CONSTITUTION:Based on the decision of readout data on an outgoing path, OK (good decision result) or NG (no good result) signals are given to a data decision section DTD for storage. In case of the OK signal, a data reproduction DR transfer a good data to a buffer BF and in case of the NG signal, the following processing is proceeded. A readout data at return path is stored in a register RG1. A control section HCT instructs the generation and output of a data reproduction instructing signal DRS to the DTD. Only when the result of the DR is NG, the DRS is generated. The data in a register RG2 is decided at the DR the same as mentioned above and informs OK/NG to the DTD. After the DTD gives the data reproduction instruction signals twice, the DTD decides if a good data is in the buffer and informs the final results F-OK/NG.
