Embodiment Construction

[0025] Please refer to FIG. 1 , the optical drive loading / exiting testing device 20 is connected to multiple optical drives, and sends loading / exiting commands to the multiple optical drives.

[0026] The optical drive in / out testing device 20 includes: a selection unit 202 , a storage unit 204 , a detection unit 206 , a setting unit 208 , an instruction sending unit 210 , a timing unit 212 , a display unit 214 and a control unit 216 . The selection unit 202 is configured to select one of the multiple optical drives as the current optical drive according to a predetermined sequence. Here, three optical drives 10a, 10b and 10c are taken as an example for illustration.

[0027] The selection unit 202 sequentially selects the three optical drives 10a, 10b and 10c according to a predetermined order for testing. The predetermined sequence may be: first select the optical drive 10a, followed by the optical drives 10b and 10c, after the selection of the optical drive 10c is complete...

Abstract

A test device of CD drive in/out tray consists of selection unit for selecting out one set of multiple optical drive to carry out test and for setting selected CD drive as current optical drive, command sending unit for sending in/out tray command to current CD drive for driving CD drive to be in/out tray, detection unit for detecting whether in/out tray of CD drive is finished or not, timing unit for recording total in/out tray time from receiving command to action finishing, control unit for controlling said selection unit to select next CD drive to be tested according to preset sequence.

Description

【Technical field】 [0001] The invention relates to an optical drive test device and method, in particular to an optical drive in / out chamber test device and method. 【Background technique】 [0002] Optical disc storage has the characteristics of large capacity and long storage time, and is suitable for storing large amounts of data, such as sound, images, animations, and videos. [0003] Optical drive is a device for reading information in optical discs. In order to ensure the quality of optical drives entering the consumer market, optical drive manufacturers must conduct quality inspections on optical drives before leaving the factory, that is, use optical drive testing equipment and programs. Item performance is tested. For example, the CD-ROM includes a loading / exiting control unit to control the loading / exiting of the CD-ROM. Every time the disc is placed and taken out, the bin entry / exit action must be carried out. If the bin entry / exit control unit is abnormal, the opt...
