Embodiment
The method of temperature of the present invention in a kind of adjustment one optical information regenerator is provided.The method according to this invention can be executed in typical optical regeneration device.That is this optical information regenerator comprises a Spindle Motor (Spindle motor), an optical information acquisition component (for example, optical read/write head) and a memory buffer.This Spindle Motor places the optical data recording medium in this optical data regenerator to rotate in order to driving.This optical information acquisition component is recorded in data on this optical data recording medium in order to acquisition.This memory buffer is used for temporary transient storage from this optical information acquisition component from data that this optical data recording medium captured.In the process of optical information regeneration, in order to handle the internal processor or the ppu of the data that this optical information acquisition component captured, required data of taking-up in this memory buffer then.
Steps flow chart according to a preferred embodiment of the present invention is shown in Fig. 1.Execution in step S10 at first, set the rotating speed of this Spindle Motor operates under an existing rotating speed according to a preassigned pattern, for example, according to static line speed (Constant linear velocity, CLV) pattern or fixed angles speed (Constant angular velocity, CAV) rotating speed of this Spindle Motor of mode initialization.
Then whether execution in step S12 detects the interior temperature of this optical information regenerator up to a first threshold.The needs of this optical information regenerator reality need be looked by this temperature detection place, that is the placement of temperature sensor (Thermal sensor).Generally, temperature sensor is good with the temperature that measures nearly this optical information acquisition component place.
If the result of step S12 is for certainly, execution in step S14 then removes the preassigned pattern of the rotating speed of setting this Spindle Motor.Execution in step S16 after the step S14, with the speed setting of this Spindle Motor at a desired speed.Execution in step S18 after step S16 in one first scheduled period, stops the running of this optical information acquisition component.
During step S18, the thermal source of this optical information regenerator, that is this optical information capture device decommissions, associated component also decommissions in the lump simultaneously.By this, the temperature in this optical information regenerator can be not again promote because of the heat that is caused in this optical information acquisition component operating period.
By this, the temperature in this optical information regenerator is driven and the air-flow that optical data recording medium caused that rotates cools off decline at the Spindle Motor of this desired speed by speed setting.About optical data recording medium (discs) when rotated, can cause the correlation technique content of air-flow, please refer to Japanese patent publication 10-092166 number and 62-052785 associated documents, not repeat them here.
In the process of the temperature in adjusting this optical information regenerator, in order to make this memory buffer that the situation of data shortage not take place, in one embodiment, after step S18, continue and carry out step S20, in one second scheduled period, the running of opening this optical information acquisition component.During step S20, this optical information acquisition component continues acquisition data from this optical data recording medium, and with the data storing that captured in this memory buffer.By this, make this memory buffer that the situation of data shortage can not take place.
In one embodiment, the execution in step that after step S20, continues S22, whether the temperature that detects in this optical information regenerator reduces to one second threshold value.If the result of step S22 is for negative, then repeated execution of steps S18 is to step S22.If the result of step S22 is for certainly, execution in step S24 then recovers to set the preassigned pattern of the rotating speed of this Spindle Motor and the running of opening this optical information acquisition component.
The DVD CD writers that below will lift one 12 times of speed is the example explanation, further specifies various situation conditions mentioned in the detailed description of foregoing invention.
Temperature in the DVD CD writers of these 12 times of speed in case up to 80 ℃, promptly may cause crashing or the intraware damage because of overheated.Use the method according to this invention, above-mentioned first threshold is made as 75 ℃, and the second above-mentioned threshold value is made as 72 ℃, and the first above-mentioned scheduled period is 1 second, and the second above-mentioned scheduled period is 1 second.
At first, operate under an existing rotating speed according to the rotating speed of this Spindle Motor of fixed angular speed mode initialization.General cooperate 12 times when fast, the rotating speed of Spindle Motor is up to 7200rpm.
Then, whether detect the interior temperature of these 12 times fast DVD CD writers up to 75 ℃.If these the 12 times interior temperature of fast DVD CD writers are up to 75 ℃, then remove the fixed angular speed pattern of the rotating speed of setting this Spindle Motor.Thereupon, with the speed setting of this Spindle Motor at the desired speed than low speed, for example 3600rpm.And, stop the running 1 second by a definite date (first scheduled period was 1 second) of the optical read/write head of these 12 times of fast DVD CD writers.By this, the temperature in these 12 times fast DVD CD writers can be not again promote because of the heat that is caused in optical read/write head operating period.Also by this, the temperature in these 12 times fast DVD CD writers is driven and the air-flow that discs caused that rotates cools off decline at the Spindle Motor of this desired speed by speed setting.
Stop after the running 1 second by a definite date of this optical read/write head, the running 1 second by a definite date (second scheduled period was 1 second) of and then opening this optical read/write head allows memory buffer in these the 12 times fast DVD CD writers that the situation of data shortage can not take place.
Then, stop the running 1 second by a definite date of this optical read/write head repeatedly, then open the running 1 second by a definite date of this optical read/write head, the temperature in these 12 times fast DVD CD writers is reduced to 72 ℃.When the temperature in these the 12 times fast DVD CD writers drops to 72 ℃, recover the fixed angular speed pattern of the rotating speed of this Spindle Motor of setting, and the running of opening this optical read/write head.
Significantly, use the method according to this invention, optical information regenerator still can be kept running, and can not crash because of overheated causing, and can keep the data that are recorded on the optical data recording medium and play (regeneration) constantly.
By the above detailed description of preferred embodiments, be to wish to know more to describe feature of the present invention and spirit, and be not to come category of the present invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain the arrangement of various changes and tool equality in the category of the claim of institute of the present invention desire application.
