High-Power Red Laser Diode Supports ×16-Speed DVD Recording

SLD1236VL

Maximum optical power output :

250 mW (in pulse drive mode)

The DVD recording market is developing rapidly.

Following the ×4, ×8, and ×12 speeds, high-speed recording has al-

ready evolved to the ×16-speed level.

To respond to this market trend, Sony has now developed the

SLD1236VL 250 mW optical power output laser diode that supports

×16-speed DVD recording.

High-temperature (75°C) operation

guaranteed

New user-friendly actual refracting

waveguide window structure

In addition to the optical power output being increased by 50 mW over

earlier products, the SLD1236VL also achieves guaranteed operation

under the severe environmental conditions of temperatures up to 75°C.

Refracting Waveguide

Window Structure

Maximum Optical Power Output:

250 mW (in pulse drive mode)

High-Temperature (75°C)

Operation Guaranteed

Increasing the recording speed in

DVD+R/RW and DVD-R/RW requires

that the optical power output of the laser

diode used as the light source be

increased. This is because the material

characteristics of the recording medium

must be changed in a period of time that

becomes shorter as the recording speed is

increased. Sony has already released

laser diodes with optical power output lev-

els of 100, 140, and 200 mW to support

recording speeds of ×4, ×8, and ×12. The

SLD1236VL of this release achieves an

even higher optical power output, and can

be driven at an optical power output of

250 mW, which supports ×16-speed

recording.

When recording at speeds as high as ×16,

the heat released by the various system

components increases due to the spindle

motor that turns the disc running faster,

the laser diode power being increased, and

other changes. As a result, the ambient

temperature inside the case increases. This

there is demand for laser diodes whose

operation is guaranteed at temperatures as

high as 75°C. Sony introduced new struc-

tures in the areas surrounding the light

emitting regions of the newly-developed

SLD1236VL, and as a result, operation is

guaranteed under severe operating condi-

tions up to 75°C.

To respond to calls for the lower aspect

ratios demanded for optical pickups, Sony

has adopted, in the previously released

SLD1234VL (pulse drive: up to 140 mW)

and SLD1235VL (pulse drive: up to 200

mW), designs that reduces the radiation

angle in the perpendicular direction (θ⊥)

at the end surface of the laser. The

SLD1236VL inherits the structure that

results in the same θ⊥ angle of 17.5

degrees (typical) achieved in the

SLD1234VL and SLD1235VL, thus cre-

ating a user friendly laser diode product.

In addition, the SLD1236VL adopts a low-

loss actual refracting waveguide window

structure that improves the low threshold

current and temperature characteristics. As

a result, the SLD1236VL achieves a

threshold current of 50 mA (typical) and

current value of 130 mA (typical) in 80

mW CW drive mode. The reduction in the

threshold current also reduces the noise

levels.

Despite this being a difficult device

to design, we only had a short

development period and the road

to commercial release was peril-

ous. However, thanks to much

assistance from the staff and our

cohesion as a group, we succeed

in making it safely to commercial

release. Our next step is to proceed

with development aimed at even

higher output to support two-layer

discs.
