摘要:PURPOSE:To improve reliability of data processing by deciding a recording error at the time when recording data on an optical disc medium, and recording the same data in other area in ca of error recording. CONSTITUTION:The data nt out from a host controller 5 is transmitted to an optical disc drive device 3 through a host-device interface 4, and interface controller 6, a writing buffer 7 under the control of a write control circuit 8, and a modulating circuit 8'. This data is transformed from an electrical signal to an optical signal by a light emitting diode 9, pass through a lens 10, and is recorded as data 12 in a data area 11 of the optical disc medium 2. Simultaneously, in ca the state of a reflecting light that pass through a lens 13 and is detected by a detector 14 is monitored by a recording error detector circuit 15, and a recording error is detected, a recording-position control circuit 16 lets a carriage 17 move to a specified recordable position in an alternate area of the optical disc medium 2 to record the data again as data 19.
