Abstract
An optical disk device records recording data transmitted from a host device onto an optical disk. Then, as a process for checking the recorded data, the optical disk device reproduces the data from the optical disk to perform a Verify process in a recording quality determination unit, while transmitting the reproduced data to the host device. The host device performs a Compare process to compare the reproduced data transmitted from the optical disk device with the recording data transmitted to the optical disk device. At least if it is determined to be poor quality as a result of the Verify process by the recording quality determination unit or if it is determined that the data do not match as a result of the Compare process by the host device, the corresponding data is alternately recorded in an alternate area of the optical disk.
