Abstract: An optical information storing medium and an optical information recording/reproducing apparatus are provided to maintain consistency with a different kind of a recording medium by causing a data recording/modulating method in a part of a lead-in area and a data recording/modulating method in a user data area to coincide with a recording/modulating method of a recordable optical information storing medium. An optical information storing medium includes a lead-in area, a user data area and a lead-out area. Information data, which is not changed for the same physical format, is recorded in the whole lead-in area or a part of the lead-in area. A data recording/modulating method in the lead-in area is different from a data recording/modulating method in remaining areas. The area where the information data not changed for the same physical format is recorded is an area where information related to the optical information storing medium is recorded.

Abstract: An optical reproducing apparatus capable of discriminating a track and a track discrimination method therefor are provided to discriminate the track by judging whether a track which is currently tracked and rotated by a track discriminating circuit is a land track or a groove track without detecting an address. A pickup unit(210) picks up and tracks an optical disc. A track discriminating unit(220) processes a light-receiving signal inputted from the pickup unit(210), and outputs a discrimination signal for discriminating a kind of a track tracked by the pickup unit(210). If the discrimination signal outputted from the rack discriminating unit(220) has the first logic level, a main control unit(240) judges the track tracked by the pickup unit(210) as a land track. If the discrimination signal has the second logic level, the main control unit(240) judges the track as a groove track.

Abstract: A Viterbi detecting device and a method are provided to process multiple bits in one operational clock by using a supplementary clock which is 1/n of a main clock, and to remove a path of a signal having a shorter period than an undiscovered input code, thereby increasing an operational speed. A divider(660) generates a supplementary clock produced by dividing a main clock in 1/n(n is a natural number of more than 2). A serial to parallel converter(620) outputs a branch metric calculated at main clock interval in n state unit. A parallel to serial converter(650) converts output data of a path memory(640) into serial data at supplementary clock interval. When a path selected by an ACS(Adding Comparing Selecting) unit(630) is operated with an existing clock, a path of a signal which is not matched with a code condition is removed.

Abstract: A device and a method for reproducing data are provided to realize a reference level which optimizes channel properties, thereby initializing an input level value such that a Viterbi decoder can normally operate even though an input signal is in abnormal state. A controller(640) generates a binarizer selection signal(644) for determining an operational mode of a channel identifier(600) and a reset signal(642), based on a user input(643). In case of the type of an input binary signal, the controller(640) receiving the user input(643) outputs the selection signal(644), while the channel identifier(600) receiving the signal(644) uses one of an output signal(106) of a Viterbi decoder(140) and an output signal(631) of a slicer(630) as an input signal. In case of a type of a signal used as a level value of the Viterbi decoder(140), the controller(640) outputs the reset signal(642), while the channel identifier(600) receiving the reset signal(642) determines whether to use a predetermined initial level value as the level value of the Viterbi decoder(140) or to use a value generated on the basis of binary signals(631,202).

An input signal quality determining unit(480) calculates quality of the input signal based on the updated filter coefficient value. A data detector(422) converts the input signal into digital data. A channel characteristics detecting filter(424) calculates the estimate signal by using the converted digital data and the certain filter coefficient.
