INFORMATION STORING APPARATUS
A disclosed information storing apparatus includes a rotatably-mounted memory medium; a carriage arm having a head at its tip; a flow rectifying wall configured to lead a partial airflow of a rotational airflow flowing in a rotation direction of the memory medium and rectify the partial airflow, and including an inflow opening from which the partial airflow flows into the inner path of the flow rectifying wall and an outflow opening from which the partial airflow having passed through the inner path flows out; and a circulation filter. The inflow opening and outflow opening are disposed on an upstream side and a downstream side, respectively, of the rotational airflow with respect to the carriage arm. The circulation filter is disposed in such a position that the led partial airflow flows into the circulation filter in a direction opposite to the flow direction of the rotational airflow.
1 . An information storing apparatus comprising:
a rotatably-mounted memory medium;
a carriage arm having, at a tip thereof, a head configured to perform at least one of reproduction of information recorded on the memory medium and writing of information on the memory medium, the carriage arm being movable so as to move the head to a predetermined position relative to the memory medium;
a flow rectifying wall disposed along an outer circumference of the memory medium, configured to lead a partial airflow which is part of a rotational airflow flowing in a rotation direction of the memory medium and rectify the partial airflow, and including an inflow opening from which the partial airflow flows into an inner path of the flow rectifying wall and an outflow opening from which the partial airflow having passed through the inner path of the flow rectifying wall flows out; and
a circulation filter;
wherein the inflow opening is disposed on an upstream side of the rotational airflow with respect to the carriage arm, and the outflow opening is disposed on a downstream side of the rotational airflow with respect to the carriage arm, and
the circulation filter is disposed in such a position that the partial airflow led into the inner path of the flow rectifying wall flows into the circulation filter in a direction opposite to a flow direction of the rotational airflow.
2 . The information storing apparatus as claimed in claim 1 , wherein the outflow opening has one of an airflow path oriented in a direction perpendicular to the flow direction of the rotational airflow and an airflow path inclined in such a manner that a direction in which the partial air flow flows out is inclined to a side of the flow direction of the rotational airflow.
3 . The information storing apparatus as claimed in claim 1 , wherein the inflow opening has an airflow path along a direction tangent to the flow direction of the rotational airflow.
