DISC DRIVE APPARATUS, AND METHOD FOR TIMING RECALIBRATION IN A DISC DRIVE APPARATUS

摘要

A disc drive apparatus (1) is described, comprising a data engine system (20) and a data processing system (30) in data communication with each other. The data engine system (20) and the data processing system (30) are also in a conferring communication with each other regarding the timing of recalibration. The data engine system (20) is designed to determine (step 120; 320) a moment when a recalibration procedure would be desirable, and to send (step 121; 321) a recalibration request signal to the data processing system (30). The data processing system (30) may or may not send (step 230; 430) a recalibration permission signal to the data engine system (20). The data engine system (20) only performs (step 132; 332) a recalibration procedure after having received the recalibration permission signal from the data processing system (30).
