Pickup inspection apparatus

A pickup module inspection apparatus to inspect a combo-type pickup module that is compatible with different types of discs using corresponding optical pickups, the apparatus comprising:

• a machine unit to receive the pickup module to be inspected, to position the pickup module to read data from a received disc, and to rotate the received disc in order to read data from the received disc;
• a measuring unit to control the received pickup module to read the data from the received disc and to output measurement information that results from the read data;
• and
• a controller to select one of the optical pickups that is compatible with one of the types of discs but not another of the types of discs, to activate the selected optical pickup, to control said measuring unit and said machine unit to read the data from the received disc using the activated optical pickup, and to compare the output measurement information with predetermined standards corresponding to the selected optical pickup.

A computer readable medium encoded with processing instructions for implementing a method of inspecting a combo-type pickup module that is compatible with different types of discs using corresponding optical pickups performed by a computer in a pickup module inspection apparatus, the method comprising:

• selecting one of the optical pickups that are compatible with different types of discs;
• setting a received combo-type pickup module to active the selected optical pickup that is compatible with the one of the types of discs but not with another of the types of discs;
• controlling a machine unit to rotate a test disc and to position the received combo-type pickup module to read data from the test disc using the received pickup module;
• controlling a measuring unit to receive the data read using the received pickup module, to perform an inspection corresponding to the selected optical picup using the read data, and to output inspection data;
• and
• comparing the inspection data with stored data to determine whether the pickup module has a defect.
