Abstract
An information reproduction unit has a data read means with a pickup for intermittently reading data recorded on a storage medium, a write means for writing the data in a memory, and a reproduction means for sequentially reading out the data written in the memory. The unit also has a defect detection means for detecting a defect of the storage medium during a data read waiting period. The defect detection means may determine the presence of a defect based on a readout result provided by the data read means. The unit may further include a storage means for storing a defect position information. Furthermore, a read characteristic may be adjusted on reading data at the defect position on the storage medium.
