Title: Optical crosstalk attenuation for an optical disk drive
IPC: G11B7/09
Filed: 1992-07-23
Abstract: A method for attenuating optical crosstalk induced 
components of a focus error signal in an optical disk drive of 
the type having a grooved optical disk with servo tracks and 
tracking and focus servo systems controlled by a digital signal 
processor. A calibration operation is performed whenever a new 
disk is inserted into the track. During the calibration 
operation, the disk is scanned about a tracking axis at a track 
crossing frequency greater than the focus servo system bandwidth. 
The focus error signals produced when the disk is scanned are 
filtered about a pass band including the track crossing 
frequency. Crosstalk values equal to values of the filtered 
focus error signals are determined as a function of corresponding 
values of the tracking error signals, and are stored in memory. 
A correction operation is performed while reading and writing 
data on the disk. During the correction operation, the crosstalk 
values are read from memory as a function of corresponding values 
of the tracking error signals, and summed with the focus error 
signals.

Abstract: A method for controlling a tape motor using a
microcontroller for feeding tape in correspondence to
printing of an indeterminate length of printing on the tape
by a print drum utilizes a sensor for indicating a tape
condition which changes in accordance with the engagement of
a printing portion of the print drum with the tape. An
optical sensor and slotted disk provide signals indicative
of the rotation of a motor shaft of the tape motor. At least
first and second counters are provided for counting signal
pulses from said optical sensor corresponding to the passage
of slots during rotation of the motor. From these counts
and the indication of printing by the print drum, the micro
controller can develop the timing of control signals for
controlling the motor in correspondence to the length of
printing on the tape.

Abstract: An external modulation fiber optic transmitter includes an optical source, a predistorter
for generating a distortion cancellation signal in response to a radio-frequency input, an electro-optic
modulator for modulating the optical signal in response to the distortion cancellation signal,
and an adaptive predistortion control circuit for providing a predistortion control signal to the
predistorter. The adaptive predistortion control circuit includes a receiver for receiving the
modulated optical signal output by the modulator, a filter for filtering the intermodulation
distortion from the modulated optical signal to obtain a first distortion component, a distortion
generator for receiving the radio-frequency input signal from the predistorter and generating a
second distortion component in response to the radio-frequency input signal; a mixer for
synchronously demodulating a product of the first and second distortion components to obtain
a correction signal; and a lowpass filter and integrator for generating the predistortion control
signal in response to the residual intermodulation distortion in the output of the electro-optic
modulator. The predistorter modifies the distortion cancellation signal in response to the
predistortion control signal, thereby reducing distortion of the modified optical signal. Similarly,
a method of adaptive predistortion control for optical external modulation includes the steps of
generating a predistortion control signal; modulating an optical signal using the predistortion
control signal; transmitting the modulated optical signal; receiving the modulated optical signal;
filtering the modulated optical signal to obtain a first distortion component; generating a second
distortion component using the predistortion control signal; synchronously demodulating a
product of the first and second distortion components to obtain a second order correction signal
and a third order correction signal; integrating the second order correction signal to generate a
modulator bias control signal; and integrating the third order correction signal to control
parameters of the predistorter, thereby modifying the predistortion control signal in response to 
the modulator bias control signal to reduce distortion of the modulated optical signal.

Abstract: Cryogenic apparatus comprising a liquefier (11) and a
dual column system distillation column system (81) selectively
operates in a first mode during which only liquid nitrogen (130) is
produced and a second mode during which liquid nitrogen (130)
and liquid oxygen (106) are produced. By adjusting the time of
operation in each mode, any ratio of liquid nitrogen (130) to liquid
oxygen (106) greater than the ratio achieved during the second
mode of operation can be achieved. In the first mode of operation,
a condenser (88) is used to condense the lower pressure column
gaseous nitrogen into lower pressure column nitrogen condensate
(122) against at least a portion (146) of the crude oxygen liquid
(92) from the higher pressure column (82), at least a portion (108)
of the oxygen-enriched liquid (104) from the lower pressure
column (86), at least a portion (138) of the liquefied air (134), or
mixtures thereof. In the second mode of operation, said condenser
(88) is not used; instead, all of the crude oxygen liquid (92) is
introduced into the lower pressure column (86), which produces a
liquid oxygen product (106) and a low pressure overhead waste
stream (152) containing nitrogen.
