    • The present invention provides a magnetic disk inspection method and its system suitable to supply magnetic disks stored in a cassette to a plurality of inspection devices and collects inspected magnetic disks from the inspection devices. The cassette in which uninspected magnetic disks are stored is taken out from a cassette housing unit and transferred to any one of a plurality of optical inspection units. The optical disk inspection unit to which the cassette with the uninspected magnetic disks stored therein is transferred, takes out an uninspected magnetic disk and inspects both surfaces thereof. The magnetic disk whose both surfaces are inspected and which is determined as a non-defective product is stored in a cassette for collecting non-defective magnetic disks. The cassette is transferred from the optical inspection unit to the cassette housing unit. The transferred cassette is housed in the cassette housing unit.
    • 本发明提供了一种磁盘检查方法及其系统,其适用于将存储在盒中的磁盘提供给多个检查装置,并从检查装置收集检查的磁盘。 存储非预期磁盘的盒式磁带从盒式存储单元中取出并传送到多个光学检查单元中的任意一个。 将其中存储有未预期磁盘的盒带转移到的光盘检查单元取出未检测的磁盘并检查其两个表面。 检查其两个表面并被确定为无缺陷产品的磁盘被存储在用于收集无缺陷磁盘的盒中。 盒式光盘从光学检测单元传送到盒式存储单元。 转移的盒式磁带被容纳在盒式存储单元中。
