Controller for information recording and reproducing device and control method for the information recording and reproducing device

The control device for an on-board information recording and reproducing device, further comprising a solar cell mounted on the vehicle to serve as a power source for starting rotation of the bearing parts.

A control method for an on-board information recording and reproducing device including disk media holding information, a head for recording or reproducing information from the disk media, a carriage turning to position the head on a surface of the disk media, a bearing part permitting the carriage to turn, a spindle motor for rotatingly driving the disk media, and a bearing part of the spindle motor, the method comprising the steps of:

• detecting a manner before a vehicle continuously causes vibrations;
• and
• starting rotation and/or starting swings the bearing part of the spindle motor and/or the bearing part of the carriage on the basis of the detecting the manner in advance.

A control method for an on-board information recording and reproducing device including disk media holding information, a head for recording or reproducing information from the disk media, a carriage turning to position the head on a surface of the disk media, a bearing part permitting the carriage to turn, a spindle motor for rotatingly driving the disk media, and a bearing part of the spindle motor, the method comprising the steps of:

• detecting, by means of an acceleration sensor provided on a vehicle or the information recording and reproducing device, whether acceleration has exceeded a predetermined value;
• and
• starting rotation and/or starting swings the bearing part of the spindle motor and/or the bearing part of the carriage on the basis of the detecting signal.

A control method for an on-board information recording and reproducing device including disk media holding information, a head for recording or reproducing information from the disk media, a carriage turning to position the head on a surface of the disk media, a bearing part permitting the carriage to turn, a spindle motor for rotatingly driving the disk media, and a bearing part of the spindle motor, the method comprising the steps of:

• detecting a vehicular velocity by means of a velocity meter mounted on a vehicle;
• and
• rotating and/or turning the bearing part of the spindle motor and/or the bearing part of the carriage on the basis of the detecting of the vehicular velocity while the vehicle is traveling.
