摘要： A cleaner unit is provided for applying a liquid cleaning solution onto the surface of an information disk, such as a so-called compact laser disk or the like. The cleaner unit comprises a housing with a rotatable spindle adapted to support the information disk in a generally horizontal orientation, in combination with a circulation system having a rotatable pump impeller for spraying a jet of a cleaning solution onto the underside of the disk near the spindle. A drive motor is operated by a control circuit for initially rotating the spindle and impeller in a first direction for spraying the cleaning solution against the spinning disk, with the rotational disk movement causing the cleaning solution to spread radially outwardly as a film over the underside disk surface. The cleaning solution is thrown from the disk periphery and is captured by an outer contoured deflector shroud for recirculation to the pump impeller. At the conclusion of a short cleaning cycle, the control circuit reverses the direction of spindle and impeller rotation to spin the disk in an opposite or second direction for the duration of a short dry cycle, without applying cleaning solution to the disk.

摘要： A cleaner unit is provided for applying a liquid cleaning solution onto the surface of an information disk, such as a so-called compact laser disk or the like. The cleaner unit includes a housing with a rotatable spindle (22) adapted to support the information disk in a generally horizontal orientation, in combination with a circulation system having a rotatable pump impeller (24) for spraying a jet of a cleaning solution onto the underside of the disk (12) near the spindle. A drive motor is operated by a control circuit for initially rotating the spindle and impeller in a first direction for spraying the cleaning solution against the spinning disk, with the rotational disk movement causing the cleaning solution to spread radially outwardly as a film over the underside disk surface. The cleaning solution is thrown from the disk periphery and is captured by an outer contoured deflector shroud (99) for recirculation to the pump impeller. At the conclusion of a short cleaning cycle, the control circuit reverses the direction of spindle and impeller rotation to spin the disk in an opposite or second direction for the duration of a short dry cycle, without applying cleaning solution to the disk.
