A method for reading data from an unbalanced disk in a disk drive is disclosed. The method includes the steps of measuring a degree of unbalance of the disk while starting up a rotation of the disk, determining a suitable rotating speed for error-free reading (e.g., a maximum error-free reading speed) corresponding to the measured degree of unbalance, based on a previously stored relationship between degree of unbalance and suitable rotating speed, and beginning a reading operating while rotating the disk at the determined rotating speed. In accordance with the method, it is possible to suppress an unbalanced disk from vibrating, thereby achieving a stable data reading from the disk.
