Abstract: An optical recording medium has a user data area and a lead-out area, wherein the user data area and the lead-out area each has grooves and lands formed thereon. Wobbles are formed on at least one lateral surface of grooves of the user data area and the lead-out area, and configured such that wobble characteristics are made different between the user data area and the lead-out area. Different types of wobbles are formed on the grooves of either the user data area or the lead-out area, thereby preventing an optical pickup that performs recording/reproduction from deviating from the user data area. Also, in a multi-layer optical recording medium, a whole area of a recording layer is configured to have a same condition, thereby preventing deterioration in reproduction and/or recording due to a difference in light power transmittance of another recording layer.

Abstract: A method for managing a network in which Bluetooth equipped devices are linked together when the network master cannot serve as a master. During normal operation, the network master updates the backup master rank information when the network master disappears, in a predetermined cycle, according to link information, such as received signal strength indication (RSSI) or link quality, transmitted from the Bluetooth equipped devices serving as a slave. When power of the network master is exhausted, or when the network master leaves the network operating region, a new master is selected from the remaining slaves according to the backup master rank information, thereby reconfiguring a network around the new network master. The method enables proper designation of a new master when a preexisting network master leaves the network operating region, thereby increasing a probability of holding connection throughout the network.

Abstract: Provided is an apparatus and method for all-optically controlling both a gain and a gain flattening. The apparatus includes: a first amplifier automatically controlling a gain of the apparatus through a feedback loop while amplifying a received optical signal; a fixed gain flattening unit receiving the amplified optical signal from the first amplifier and compensating for the gain according to a wavelength of the received optical signal; and a second amplifier automatically controlling the gain through a feedback loop while amplifying the optical signal input from the fixed gain flattening unit. Accordingly, even if the number of channels of an input WDM optical signal varies, both of a gain and a gain flattening can be all-optically controlled.

Abstract: The present invention relates to an apparatus for controlling temperature of an optical module using an uncooled laser diode. A first setup unit for establishing low-temperature setup voltage and a second setup unit for establishing high-temperature setup voltage determine first and second threshold voltages suitable for low-temperature and high-temperature setup voltages, respectively. First and second comparators compare the low-temperature and high-temperature setup voltages with sensor voltage received from a sensor voltage entry unit, respectively. The output signals of the comparators are applied to a logic circuit, such that the logic circuit generates on/off signals according to the result of the comparison. The logic circuit generates a high-level signal only when the sensor voltage escaped from a predetermined voltage range, and thus operates the temperature control circuit.
