Title: Optical disk and optical disk device
Inventor: HORIGOME HIDEYOSHI
IPC: G11B7/007
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To manufacture an optical disk with one laser beam by forming a track repeating a land/a groove and recording the positional information on the land/the groove by meandering of the groove. SOLUTION: A laser beam L emitted by a recording laser 7 is on/off- controlled to be emitted by an optical modulator 8 in response to a land/groove control signal S1 generated by a TG 13 based on a clock CK as a reference. The beam L is displaced in its optical path to be emitted by an electroacoustic optical element 9 with a wobble signal WB generated by a wobble signal generating circuit 15, and is bent by a mirror 10 to be emitted to a master disk 4. Then, the track is formed by moving the mirror 10 and an objective lens 11, while the groove is formed in a fixed cycle in the track. Moreover, the groove is made to meander by the signal WB, and the positional information of a sector and a track address, etc., of each groove is recorded. Thus, only by controlling such a single beam L, the master disk 4 can simply be manufactured.

Title: Method and system for adaptive modulated transmission
Inventor: NAITO MASASHI
IPC: H04J3/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To improve error rate and information transmission efficiency by easily applying an adaptive modulating method, even to a TDMA-FDD system at different upper and lower frequencies to be used by demodulating a signal, corresponding to a reception time slot from a TDMA processing part. SOLUTION: A timing signal showing the reception time slot of a present station is applied from a TDMA processing part 5 to an adaptive demodulation part 4. Thus, the demodulation part 4 extracts the signal of a time slot designated by that timing signal from orthogonal signals I and Q outputted from an RF part 2. Afterwards, that modulating system is detected, the data are demodulated and sent to the TDMA processing part 5 and an MI (modulating system request signal) for MS transmission from a base station is sent to a control part 6.  Thus, by shortening a frame cycle, the state change in a propagation path between two transmission frames is sufficiently reduced and even in the case of the TDMA-FDD system of which the frequencies to be used for up and down are made different, the adaptive modulating system can be easily applied, so that the error rate and information transmission efficiency can be improved.
