As CD, the CD of DVD etc. has been enumerated for example CD-ROM, the CD of reading special use of DVD-ROM etc., CD-R, the CD of the Worm type of DVD ± R etc., CD-RW, DVD ± RW, the various CDs of the CD that writes/delete the type of rewriting of DVD-RAM etc. etc.These CDs form following medium, wherein, and the processing of adopting CD player that data are reproduced etc.

" CD-ROM ", or " ROM " of " DVD-ROM " be the abbreviation of " Read Only Memory ", CD-ROM, or DVD-ROM be read special-purpose.In addition, " CD-R ", " R " of " DVD ± R " be the abbreviation of " Recordable ", CD-R, or DVD ± R can write.In addition, " CD-RW ", " RW " of " DVD ± RW " be the abbreviation of " ReWritable ", CD-RW, or DVD ± RW can rewrite.In addition, " DVD-RAM " is the abbreviation of " DigitalVersatile Disc Ramdom Access Memory ", read-write deletion.

CD player be as can adopting for example CD, player of any one among the DVD or two s' CD etc. and constituting.The CD player, DVD player can adopt the player of CD and two kinds of CDs of DVD, according to for example with the PC of notebook type, the mode of assemblings such as the PC of desktop type is used.PC is the abbreviation of personal computer (Personal Computer).

In addition, on the player main body that constitutes player, be provided with the pallet that to install CD.This pallet is in the position of regulation, as can installing CD, or the form of DVD and forming.Such pallet is arranged at the front face side of player main body.More particularly, the front in the player main body that constitutes player is provided with pallet, and this pallet can be installed on CD in the CD player, discharges the pallet of CD in the CD player.

In addition, the basic middle place in the CD player main body is provided with the turntable that drives CD.In addition, the pick-up that carries out the action of read output signal from CD is arranged on the CD player main body.In addition, the rear portion in CD player is provided with circuit.In addition, the trailing flank in CD player is provided with splicing ear, and this splicing ear can be connected with basic computer.

At Worm type CD, the CD of recordable type that maybe can rewriting type CD etc., when recording data etc., the laser of bigger output valve shines on the CD from the laser diode of pick-up, at the CD identifying recording layer.When the CD identifying recording layer,, penetrate the laser of bigger output valve from the laser diode of pick-up.

For laser diode from pick-up, penetrate the laser of the bigger output valve of output, laser diode necessarily requires more electric current.The electric current that flows through laser diode flows through from the integrated circuit on the base main body that is loaded into forming circuit.Thus, when at the CD identifying recording layer,, flow through more electric current from the integrated circuit of forming circuit.Because such a formation when the CD identifying recording layer, from laser diode, with integrated circuit, produces more heat.Laser diode and integrated circuit constitute the electrical/electronic components that produces more heat.

Also the electrical/electronic components of other beyond laser diode and the integrated circuit produces heat.Laser diode, the thermal value that produces with integrated circuit substantially exceeds from the heating of laser diode and integrated circuit electronic unit generation in addition.In addition, when being the CD identifying recording layer, relative CD player main body, pallet turns round in closing state, thus, and the heat that produces from laser diode, the heat that produces from integrated circuit etc. is accumulated in the internal stent that constitutes the CD player main body.

When from laser diode, penetrate the light time, the oscillation wavelength of laser diodes depends on temperature.Thus, if bigger variation takes place the temperature of laser diode, then the Wavelength of Laser that penetrates from laser diode also changes.If by the heat that laser diode itself sends, the savings laser diode then changes from the Wavelength of Laser that laser diode penetrates.If produce such situation,, penetrate the laser of constant wavelength then not from laser diode.

Temperature as the heater that prevents pick-up etc. rises, prevent to rise because of excess temperature, the device of the characteristic degradation of heater, include following CD drive, in this CD drive, on the axle identical with the turning axle of Spindle Motor, screw propeller (propeller) is set, or fan, follow the rotation of Spindle Motor to produce wind, this wind is positioned at the heater of pick-up, motor, circuit etc., these heaters is cooled off (for example open the 1st, 3 page of 2002-25243 document with reference to the open communique spy of Jap.P., Fig. 6,11,14,15 etc.).

But, in the CD player in above-mentioned past, owing to, put aside heat easily, so be difficult to carry out laser diode, the heat release of integrated circuit in the inside of the support that constitutes the CD player main body.If form and carry out laser diode, the structure of the heat release difficulty of integrated circuit then has laser diode, integrated circuit, the danger of the accumulation of heats such as heat of sending because of itself.

As mentioned above, owing to work as from laser diode, when penetrating laser, then the oscillation wavelength of laser diodes depends on temperature, so if the temperature variation of laser diode is bigger, then the Wavelength of Laser that penetrates from laser diode also changes.If because of the heat that sends by laser diode itself, the temperature anomaly height of laser diode then changes from the Wavelength of Laser that laser diode penetrates.Producing such occasion,, penetrate the laser of constant wavelength not from laser diode.

In the state action of laser diode,, has the danger that CD has a negative impact in the occasion of CD identifying recording layer to laser diode at abnormal high temperature.For example be that laser diode is under the condition of state of abnormal high temperature, in the occasion of CD identifying recording layer, to the performance of laser diode, lifetime of LD, quality that is recorded in the data on the CD etc. causes bigger influence.Like this, if be at laser diode under the condition of state of abnormal high temperature, at the CD identifying recording layer, then have following danger, that is, form lifetime of LD and shorten, in addition, the performance change of laser diode, the ungratified CD of the reliability of record.

If specifically describe, be that then when writing data, the electric current of bigger current value flows through the integrated circuit that control circuit adopts, with the laser diode that is connected with integrated circuit on the Worm type optical disk of CD-R etc.So, integrated circuit and laser diode heating.In the occasion of such state, the heat accumulation of heat that laser diode produces because of laser diode itself.In addition, follow this situation, from the heat of generations such as integrated circuit, the temperature of laser diode further rises.Because the integrated circuit heating, then the peripheral temperature of light picker rises.Be the state of laser diode abnormal high temperature,, have lifetime of LD in the occasion of CD identifying recording layer, the performance of laser diode, the quality that is recorded in the data on the CD causes the danger of adverse effect.

In order to prevent that heat from putting aside in the situation of the inside of CD player, also can the fan of cooling usefulness be set by in CD player, avoid the high temperatureization in the CD player.Such mode is for example at desk-top PC (not shown), forms the effective type of cooling.Desk-top computer is the computing machine of desktop, and the computing machine that can use on the table still, is the type that is not easy to carry.

Because desk-top relatively PC, the PC (not shown) of notebook type requires lightweight, and is lightening, so have the structure that forms the CD player that narrow type driver is set.The PC of notebook type is the structure different with desk-top PC.In the PC of notebook type, display and PC main body are structure as a whole, relative PC main body, and display is folding, thus, forms thin size.The PC of notebook type is for when it is watched in the plane, for being approximately the size of A4, or the personal computer of the widespread use of its following size, be also referred to as book type PC.Like this, importantly the integral body of the PC of notebook type is compact, can carry easily.

Because the CD player that the PC of notebook type uses is slim, old friends think that from the aspect that insufficient space is set of CD player in the CD player that the PC of notebook type uses, the aspect that the cooling fan of the temperature rising that prevents CD player is set is irrational.In the CD player of using at notebook type PC, the cooling fan that the temperature prevent CD player rises is set, must enlarge CD player parts the space is set.In the CD player that notebook type PC uses, enlargement part the increase that the space can cause the overall dimensions of notebook type PC is set.In addition, in such notebook type PC, weight increases.Because such situation is opposite with the user's of notebook type PC requirement, so do not design/make such device.

In addition, in notebook type PC, when only adopting battery, since can in long time range, use PC at least, power consumption must be suppressed with doing one's utmost, because such situation, the cooling device of the cooling fan of the electric power of consumption PC etc. is arranged at the CD player that notebook type PC uses, this situation is opposite with the user's of notebook type PC requirement, and people wish the mode by other, and the CD player of notebook type PC is cooled off.
