Abstract: A vehicle storage management system includes execution circuitry and a storage. The storage has a dynamic partition, which has been allocated in advance, and a static partition, which has been allocated in advance. The execution circuit is configured to delete data from the dynamic partition when a prescribed time has elapsed since the data was stored in the dynamic partition, reallocate a portion of the dynamic partition as an additional static partition when there is a request to install a new application, and store the new application in the additional static partition.

Abstract: An information processing device includes: a control section controlling rewriting of a recording device installed in a vehicle; and a setting section that, on the basis of a first maximum number of times of rewriting that corresponds to a first interval in which functions of the recording device are guaranteed, sets a second maximum number of times of rewriting in a second interval that is an interval that is shorter than the first interval.

Abstract: By an electronic control unit including a storage that has a shared area shared by a plurality of unspecified applications and a dedicated area used by a predetermined specific application, a use limit notification method performed in the electronic control unit, a use limit notification method, life time consumption information related to life time consumption of the storage is acquired. a shared area write limit and a dedicated area write limit are set, and an application using the storage is notified of a use limit of the storage.

Abstract: By an electronic control unit, an area allocation method, or a computer-readable non-transitory storage medium storing an area allocation program, an area securement request is accepted from an area securement request application, it is determined whether a capacity of an unallocated area of a storage exceeds a request capacity, a part of unused area of an allocated area already allocated to an area-allocated application is release as a release area, a total capacity of at least a part of the capacity of the unallocated area and a capacity of the release area is allocated as the allocated area.

Abstract: An information processing device includes a processor that manages allocation of a resource in a storage region of a storage to a plurality of functions. The storage is mounted on a vehicle and includes a dedicated region and a shared region. The dedicated region is configured to be allocated the resource configured to be exclusively used by a specific function, among the functions. The shared region is configured to be allocated the resource configured to be shared by the functions. The resource in the shared region is configured to be dynamically allocated.

Abstract: A seek time is shortened even when AV streams and non-AV streams are read continuously and alternately. When no space is available when a non-AV stream is recorded to a non-AV stream area, the non-AV stream area is closed, a non-use area is then split from the AV stream area to generate a recorded AV stream area and an intermediate state area and the AV stream area is closed. The intermediate state area is split and a new MD area and a new AV stream area are generated.

Abstract: An optical disc apparatus including a buffer controller managing a buffer memory, a disc state manager managing and searching for recordable/unrecordable states on a disc, a defect detector detecting defective sectors on the disc, and an optical disc drive device that can record even on the defective sectors. When a defective sector region i.e. a set of defective sectors exists in a wide range, file management information is recorded. If the range is narrow, recording is continued by recording dummy data on the defective sector region and resuming to record regular data upon arrival of normal sectors. The range of the defective sector region is defined as wide when the buffer memory would be exhausted on the way if the dummy data recording was continued, whereas it is defined as narrow when the buffer memory would not be exhausted.
