ABSTRACT:
A head-arm mechanism comprises a head-arm being provided with a head. The head-arm is supported so that the head-arm can rotate. The head-arm mechanism also comprises a first driver. The first driver drives the head-arm to rotate so as to make the head move on a data area of the disk during an access time. The data area is to be stored with information. In the access time the head records information on the disk or it reads information from the disk. The head-arm mechanism also comprise a second driver. The second driver drives the head-arm to rotate so as to move to a retaining or holding position so as to make the head move to a landing zone of the disk during an idle time. In the landing zone, no information is stored in the disk. In the idle time, the head does not record information on the disk nor does it read information from the disk. The head-arm also comprises a retainer or holder. The retainer or holder retains a part of the head-arm by affecting a part of the head-arm between the rotational axis and the head when the head-arm reaches the retaining position. The retainer or holder is provided in a position facing a plane of the disk.
