An optical disc apparatus reliably executes a seek operation even if an optical disc is warped. Tilt adjustment values spanning from the inner circumference to the outer circumference of an optical disc are stored. When seeking from a start address to a destination address, a tilt adjustment value A at the start address and a tilt adjustment address C at the destination address are not directly used. A tilt adjustment value k&#xb7;C (k&#x3c;1) is used during a coarse seek operation until the neighborhood of the destination address and a tilt adjustment value C is used during a fine seek operation from the neighborhood of the destination address to the destination address.

Optical disc apparatus

An electric appliance monitoring system that can report an operational state of an electric appliance includes a monitoring part and a transmission part. The monitoring part monitors the operational state of the electric appliance and outputs a detection signal to the transmission part. The transmission part transmits a signal corresponding to the detection signal output from the monitoring part.
