Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are e.g. “unselected”, “selected” or “activated”. According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don't have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. Such menu data may be stored e.g. on a Blu-ray disc.

A method and apparatus for recording on an optical recording medium, including the recording of management information, are described as a standard for the write-once Blu-ray disc. The management information is recorded in a management area of the disc, such as a temporary defect management area (TDMA), and includes record status information and update information. The record status information is a space bitmap (SBM) indicating whether a recording operation has been performed for a predetermined area of the disc, and the update information is SBM update information indicating whether the record status information is to be continuously managed. The SBM update information controls the state of an SBM-on / off function for each of a plurality of recording areas and may be in the form of either start position information and length information corresponding to the respective areas or an SBM update flag. The SBM update information is recorded in the TDMA and is stored in a memory of an optical disc recording / reproducing device for use during recording and reproducing operations. At the time of recording in the predetermined area, an SBM-on state enables a logical overwriting operation to be performed as necessary.

Disclosed herein are a recording medium, an apparatus for forming the recording medium, and an apparatus and method for reproducing the recording medium. CPI (Copy Protection-related Information), identification information (CPI_Flag) indicative of recording or non-recording of the CPI, and / or a plurality of contents specific information (CSI) with different formats are recorded in a PIC (Permanent Information & Control data) zone of a high-density optical disc such as a BD-ROM (Blu-ray Disc-ROM).

A mirror 1a transmits a cyan (Cy) ray and reflects an R ray, and a mirror 1d transmits a yellow (Ye) ray and reflects a B ray. The mirrors 1a and 1d are arranged inside a light-transmitting member 3 and are also tilted so that the light reflected from each of them is further reflected from the interface between the light-transmitting member 3 and the air and then incident on an adjacent photosensitive cell. Photosensitive cells 2a and 2d receive the light rays that have been transmitted through the mirrors 1a and 1d, respectively. No mirrors are arranged over photosensitive cells 2b and 2c. The photosensitive cell 2b receives directly incident light and the light ray reflected from the mirror 1a. The photosensitive cell 2c receives the directly incident light and the light ray reflected from the mirror 1d. Color information is obtained by making computations on the output signals of the respective photosensitive cells.

A method for optimizing a scheduler for an optical pick-up reduces switch times required for seamless video angle switching. The pick-up reads data streams from different files on an optical storage medium, e.g. Blu-Ray disc. Seamless video angle switching requires reading and buffering a new video data stream from another file, delaying the switch to be visible. Labels that mark entry points for seamless angle switching are attached to the video stream, and are stored together with the video data in a buffer. When an angle switch is requested, and thus a switch to a new video data stream, the scheduler determines the time before data from the new data stream can be buffered, detects the next label, and stores the new data beyond the label, thus flushing non-relevant parts of the previous buffer contents.
