Abstract

An air cleaning method for a storage medium drive begins by inserting, into an air inflow port provided in a housing of the drive, an air inflow nozzle which is internally provided with an ionizing electrode to generate corona discharge, charging dust particles within the apparatus by applying a voltage to the ionizing electrode. An air exhaust nozzle is inserted in an air exhaust port provided in the housing of the drive. The exhaust nozzle is internally provided with a dust collecting electrode to collect the ionized dust particles. The dust collecting electrode attracts the dust particles to the air exhaust nozzle, and the dust particles are exhausted to the external side of the drive with the air exhaust nozzle. The air inflow and air exhaust ports are then sealed.

Dependent claims

An air cleaning method for a storage medium drive, the storage medium drive having a housing, an air inflow port and an air exhaust port, comprising the steps of:

(a) inserting an air inflow nozzle for taking air into said storage medium drive through the air inflow port, the air inflow nozzle having an internal ionization electrode for ionizing dust particles within the storage medium drive;
(b) inserting an air exhaust nozzle for flowing the air out of the storage medium drive through the air exhaust port, said air exhaust nozzle having an internal dust collecting electrode for collecting the ionized dust particles within the storage medium drive;
(c) electrifying the dust particles within the storage medium drive by supplying a voltage to said ionizing electrode;
(d) collecting the dust particles by attracting the dust particles to said dust collecting electrode;
(e) exhausting the collected dust particles to outside of the storage medium drive by using said air exhaust nozzle;
(e) removing said air inflow nozzle and said air exhaust nozzle after completion of dust collection;
and
(f) sealing the air inflow port and the air exhaust port.
