Translation of "Schreibleistung" in English

Under unfavourable conditions, the performance of the papers is substantially impaired.

Better write performance can be obtained when this option is enabled.

Should this write performance be exceeded, an exchange should be made early enough.

This allows additional space to be reserved to assist in maintaining high write performance.

Sequential write performance measurements are based on Intelligent TurboWrite technology.

For the novel disk, a radius-independent value of 8.5 mW was found for the optimum recording power.

Table 4 shows that, at a fixed Cr content, the optimum recording power increases with increasing Co content.

Steeper gradients in the optimum write performance require steeper gradients of the Cr content in the radial direction.

Each SSD drive offers a total, guaranteed write performance of up to 1800 TB.

In a particularly preferred embodiment of the novel disks, the effect of Cr on the level of the read signal and on the optimal write power can consequently be compensated b a higher cobalt content in the chromium-containing (RE-TM) layers.

In Examples 5 and 6, prior art magneto-optical recording layers having a radially homogeneous composition (Example 5) and novel magneto-optical recording layers having a radially inhomogeneous composition (Example 6) are compared with one another in terms of the optimum write power required for recording.

The latter comprised a pulse code modulated laser which emitted light of the wavelength 836 nm with maximum writing power output of 10 mW.

In contrast to this, it was ascertained experimentally for a magnetic coding arrangement according to the invention that at a recording distance of 5 millimeters and a pulse length of 5 milliseconds it is sufficient to use a recording power of 0.576 watts to re-record the coding arrangement.

The advantage of such a soft-magnetic contact is that it focusses the field of a recording magnet somewhat and thereby further reduces the recording power required.

Because the Curie temperature of the disk is constant over the radius, the optimum write performance of the medium must increase in an outward direction in order to avoid large variations in the recording characteristics along the radius.

The radial sensitivity curve of the novel layers can therefore be adjusted so that recording can take place on the entire disk with the same optimal write performance, independently of the radius.

Investigations with regard to the optimum recording power were carried out for the disks of Examples 5 and 6 using a magneto-optical drive.

The optimum recording power is defined as the laser power at which the carrier of double recording frequency has a minimum.

Table 4 shows, for the layers of Example 5, the optimum recording power determined at a radially constant Cr content y, at various radii for different Co contents x.

To determine the writing power, 8 sheets of paper were placed on the one component reactive paper and placed in an electric typewriter (Olympia Standard) where letters "w" were typed as closely together as possible to cover an area of 4×4 cm, usng a constant typing pressure.

In a particularly preferred embodiment, the absolute value of the write performance can readily be adapted to the drive conditions (for example rotational speed, laser power, laser pulse time, etc.) by varying the Co content.

The detected signal was subjected to frequency analysis, the carrier at the single recording frequency and that at the double recording frequency being measured with a bandwidth of 30 kHz as a function of the recording power and of the radius.

A disk-shaped recording medium having a Cr content which increases radially outward thus shows substantially lower fluctuations of the carrier along a radius and is less sensitive to fluctuations of the recording power.

On reading back, the amplitude of the pulses of the reflected read laser light caused by the spots was measured and recorded as a function of the writing power with which the spots in question had been originally produced.
