The present invention relates to a vehicle-mounted disk playback device, and more particularly to a disk playback device having the function of locking and unlocking a vibration insulating mechanism of a playback deck. The frame defines a longitudinal vehicle axis. The 2-D seismic data may be preprocessed to enhance diffracted energy. The adjustments may have to be large to make a full or significant partial correction at the next shift. A goal implementation is included for comparing one or more telemetry parameter against at least one predetermined goal to obtain a fitness measure. The integrated circuit configured to execute wireless communication by means of magnetic field.
