Abstract: Provided is a technology relating to an image forming apparatus configured to calculate a toner usage amount per day. The image forming apparatus stores the calculated toner usage amount per day in a list when a toner usage history is permitted to be stored, and avoids storing the calculated toner usage amount per day in the list when the usage history is inhibited from being stored. When the toner usage history is permitted to be stored, the image forming apparatus extracts a feature amount indicating a toner consumption tendency exhibited by a user based on the toner usage amount per day corresponding to a predetermined period stored in the list, and avoids extracting the feature amount when the toner usage history is inhibited from being stored.

Abstract: A SYNC detection window creating section creates a SYNC window signal on the basis of the output of a counter counting a synchronized phase detection signal at a WDU cycle and the output of a counter counting WDU at a Segment cycle. On the other hand, a synchronized signal is detected from the synchronized phase detection signal on the basis of the pattern to output a detection signal. Then, the detection signal obtained during a period of generation of a SYNC window is outputted as the synchronization detection signal.

Abstract: To achieve accurate sync detection and physical address detection which is robust against disturbance such as noise or the like, four wobbles may be added to form one input to suppress the influence of disturbance such as noise or the like. Using an input bit which is robust against disturbance, a count value of a non-modulated field located before a SYNC pattern is used to generate a gate signal for sync signal detection. In this way, any detection error of a sync signal is prevented.

Abstract: A first reading signal to a fourth reading signal are acquired with a four division element from an optical disk. The first reading signal and a third reading signal are sampled and added at a predetermined timing to obtain a first addition signal, while the second reading signal and the fourth reading signal are sampled and added at a predetermined to obtain a second addition signal. A phase difference signal of the first addition signal and the second addition signal are detected by repeating comparison of the two signals until the same value is attained by differing sampling timing with respect to the first addition signal and the second addition signal when the same value is not attained in the first addition signal and the second addition signal in the comparison with the result that the tracking control is conducted based on the detected phase difference signal.
