Abstract

PURPOSE:To obtain a check system which enable a check on a position sensor system, by externally operating an accessor by putting the position sensor of the accessor in operation when the operation of the accessor is abnormal and an error signal is generated. CONSTITUTION:When the operation of an accessor accessing a data cartridge becomes abnormal and error signal 10 is generated, that is reported to a host device and control part 4, check circuit 9 and a position sensor system, such as a tachometer, are forced to keep on operating. In this state, the accessor is operated with external force, e.g. manually to check the output of the sensor system again by control part 4 and check circuit 9, so that the check system which can check the position sensor of the accessor easily can be realized.
