    • PURPOSE: A recording control device of an odd and method thereof are provided to prevent a recording error by automatically controlling recording speed according to the temperature of an optical pickup if a tray is inserted. CONSTITUTION: A loading motor(11) ejects or inserts a tray. A temperature sensor(15) detects temperature of an optical pickup(14). A controller(19) establishes a first reference temperature which automatically ejects tray and a second reference temperature which automatically controls the recording speed. If a temperature of the pickup is a first standard temperature, the controller automatically ejects the tray. If a temperature of the pickup is a second standard temperature, the controller automatically controls the recording speed.
    • 目的:提供奇数及其方法的记录控制装置,以便如果插入托盘,则根据光学拾取器的温度自动控制记录速度来防止记录错误。 构成:装载电机(11)弹出或插入托盘。 温度传感器(15)检测光学拾取器(14)的温度。 控制器(19)建立自动弹出托盘的第一参考温度和自动控制记录速度的第二参考温度。 如果拾音器的温度是第一标准温度,则控制器会自动弹出纸盘。 如果拾音器的温度是第二标准温度,则控制器自动控制记录速度。

    • PURPOSE: A tracking actuator sensitivity compensating device and a method thereof are provided to properly compensate for sensitivity even though the sensitivity of a tracking actuator is changed. CONSTITUTION: A tracking actuator sensitivity compensating device measures a sensitivity change of a tracking actuator due to a temperature change of an optical pickup. The device calculates a slope corresponding to the measured sensitivity change(S10). The device measures a current temperature of the optical pickup before a label is printed on an LSD(Light Scribe Disc)(S14). The device compensates for sensitivity of the tracking actuator based on the measured current temperature and the stored slope(S15).
    • 目的:提供跟踪致动器灵敏度补偿装置及其方法,以便即使改变跟踪致动器的灵敏度来适当地补偿灵敏度。 构成:跟踪致动器灵敏度补偿装置测量由于光学拾取器的温度变化引起的跟踪致动器的灵敏度变化。 该装置计算对应于测量的灵敏度变化的斜率(S10)。 该装置在标签被打印在LSD(光刻盘)上之前测量光学拾取器的当前温度(S14)。 该装置基于测量的当前温度和存储的斜率补偿跟踪致动器的灵敏度(S15)。

    • A hard disk drive and an auto reassignment control method thereof are provided to prevent unnecessary auto reassignment so as to improve performance such as access or data processing speed. An auto reassignment control method of a hard disk drive comprises a step of measuring a PES(Position Error Signal) value from one or more sample tracks which are set up in a disk in advance when a fault occurs during the recording and reproduction of a r/w head(S200), and a step of determining whether the hard disk drive malfunctions under the specific condition where the normal operation is impossible by comparing the measured PES value with a PES value of the sample track measured in a process and then deciding whether to perform auto reassignment.
