摘要： In a video recording apparatus which records and reproduces digital TV broadcasting, an I-picture extraction processor that extracts packets containing I-pictures by analyzing a transport stream is arranged. Then, packets containing I-pictures is output, by reading predetermined amount of recorded data from an HDD in which recorded data is stored and by detecting start information and end information of the I-pictures. A stream for special reproduction is output by repeating the above-stated processes. With such arrangement, it is possible, even if data does not contain position information of I-picture, to execute special reproduction such as fast-forwarding reproduction for TV program data that is recorded as an MPEG-formatted transport stream.

摘要： According to the present invention, there is provided an image reproducing apparatus for reproducing a digital broadcast based on the MPEG standard. When performing special reproduction by use of access-unit management information that is used to manage access units, the image reproducing apparatus reads ahead the access-unit management information and compares time stamps. As a result of the comparison, if it is judged that the absence of a piece of the access-unit management information exists, the special reproduction is then performed by use of simple information that is used to manage a stream.This makes it possible to continuously perform the special reproduction even if it becomes impossible to utilize the access-unit management information.

摘要： A magnetic disk drive has magnetic disks having tracks and a number of sectors forming each track. The tracks have an ID few track format and the drive is divided into a plurality of notches. The drive also includes a memory and a defect sector list, sector replacement list, defect track list and replacement track list, each of which is stored in the memory. Defective sectors and tracks in each notch are slipped during formatting, and further defective sectors and tracks detected subsequent to the formatting are skipped. Spare sectors in the notch are provided in a spare region to accommodate the slipped and skipped sectors and tracks, respectively. The defective sector list is supervised as a two stage table to reduce the required memory size for maintaining the list and to decrease the time required for searching the list.
