Problems solved by technology

[0005] But, during this period of time when the busy bit of the optical drive is from "busy" to "completed", the optical drive entry / exit testing device has been waiting for the change of the busy bit of the optical drive without performing other actions
That is, one optical drive in / out test device can only test one optical drive at the same time, the average test time is long, and the test efficiency is low

Embodiment Construction

[0025] see figure 1 , the optical drive entry / exit test device 20 is connected to multiple optical drives, and sends the entry / exit command 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 completed, select the optic...

Abstract

A CD-ROM drive in / out testing device, which is connected to multiple CD-ROM drives, including: a selection unit, used to select one of the multiple CD-ROM drives for testing according to a predetermined order, and the selected CD-ROM drive is the current CD-ROM drive; The sending unit is used to send the entry / exit command to the current CD-ROM drive to drive the current CD-ROM drive into / out of the warehouse; the detection unit is used to detect whether the current CD-ROM drive has entered / exited the warehouse; the timing unit is used to record the automatic entry / exit The in / out time between the sending of the command and the completion of the in / out; the control unit is used to control the selection unit to select the next optical drive in the predetermined order when the current optical drive is in the process of in / out carry out testing.

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...
