Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

Abstract: In a first recording process, an end position of a kth cell (62) is aligned with an end position (P6) of a first layer recording area (43) by adjusting a recording start position (P5) of contents data (61) in an unused area (R1) in the first layer recording area (43). In a second recording process, an mth cell over the layers is divided into two cells, and the cells are recorded in an end area of the first layer recording area (43) and the head area of the second layer recording area (46), respectively.

Abstract: A disk-layer-configuration judging unit (180) of a recording-and-reproducing apparatus (100) judges which of a one-layer disk (10) and a two-layer disk (20) is a disk in which content data is to be recorded. A system controller (280) sets a recording rate to be a conventional recording rate when the disk-layer-configuration judging unit (180) judges that the disk is the one-layer disk (10) while setting the recording rate to be a recording rate that makes the maximum recordable time twice as much as the maximum recordable time of the one-layer disk (10) when the disk-layer-configuration judging unit (180) judges that the disk is the two-layer disk (20).

Abstract: At the time of recording contents data in real time over a first layer and a second layer of a double layer recordable DVD, a first VTS is formed by contents data recorded in a first layer recording area (43) and a second VTS is formed by contents data recorded in a second layer recording area (46). In an area (55) composed of a remaining area (53) of the first layer recording area (43) and a head area (54) of the second layer recording area (46), backup information of VTSI of the first VTS and VTSI of a second VTS are recorded.

Abstract: When VOB recording has reached the vicinity of the end position P6 of a first layer recording area (43), a cell close instruction is issued to stop encode processing for forming the next VOB to be stored. At this moment, for forming the next VOB to be recorded, content data stored in a buffer memory (18A) is used to form a VOB having, for example, a shorter length than a normal VOB. The VOB is recorded in the end position of the first layer recording area. After this, a dummy cell, having dummy data is recorded in an unrecorded area (122) of the end portion of the first recording area.

Abstract: A closed GOP is arranged at a plurality of positions in a video data string (31) so that the closed GOP (32) can be recorded at the head of the recording area of the second layer of the two-layer recording disc (17) during dubbing.

Abstract: While video information is recorded onto a dual-layer recording disk (2) in real time, it is judged whether or not a layer-change is necessary. If it is judged that the layer-change is necessary, a video data string (21C) in which a closed GOP (22) is disposed at the head is generated, and the video data string is recorded into a recording area in the second layer of the dual-layer recording disk immediately after the layer-change. This allows the closed GOP (22) to be always disposed at the head of the recording area in the second layer.

Abstract: In order to record the closed GOP at the head of a recording area in the second layer of a dual-layer recording disk, dummy data is recorded into the head of a space recording area in the first layer of the dual-layer recording disk.

Abstract: An information-recording apparatus is provided with: an encoding device which obtains recording information from the outside to be recorded onto a recording medium, and encoding said obtained information to correspond to the recording format of said recording information after being recording onto said recording medium; a recording device which temporarily records said encoded recording information onto a temporary recording medium that is different from said recording medium; and a transfer/recording device which transfers and records said recording information that is recorded on said temporary recording medium onto said recording medium while maintaining at least the information amount of said recording information.

Abstract: An information recording apparatus has an HDD on which data is recorded and an interface for recording the data on the HDD. When recording the data on the HDD, the interface records on the HDD information on an RDI pack required for reproducing the data by a video recording method and information on a navi-pack required for reproducing the data by a video method.
