Summary:A method and disc reading device for detecting unbalanced disc are disclosed. The disc reading device drives the disc at a particular voltage. The disc reading device includes a first sensor, a second sensor, a cache memory, an operating unit and a data table. The first sensor and the second sensor respectively detect a first parameter and a second parameter. When the first parameter is detected to be a first predetermined value, the cache memory records the second parameter as a first corresponding value. When the second parameter is detected to be a second predetermined value, the cache memory records the second parameter as a second corresponding value. The operating unit calculates a difference between the first and the second corresponding values to obtain the balance status.
