Information recording is conducted in the form of the simple format. When the simple format is indicated, the recording control data is not recorded in a lead-in area LIA, and after the information to be recorded is recorded in a data recording area DRA, the recording control data is recorded in a recording manager area RMA and a lead-out area LOA, in the data recording area DRA, recording manager area RMA, lead-in area LIA, and lead-out area LOA, which are predetermined according to the standard format. Further, when the finalizing processing is indicated, by recording again the recording control data according to the standard format to the information recording medium in which the information recording is conducted according to the simple format, the information recording medium which can be applied to the common information recording and reproducing apparatus, is easily realized.

Recording and reproducing method of information regarding medium and information recording and reproducing apparatus

Recording and reproducing method of information recording medium and information recording and reproducing apparatus

On a record medium, record information and reservation information to perform a reserved recording operation for the record information are recorded. The reservation information has: a scheduled time to start recording onto the record medium the record information of particular one kind, which is set in advance for respective one of record mediums including the record medium, among the record information of a plurality of different kinds which are recordable on the one record mediums; and a scheduled time to stop recording onto the record medium the record information of the particular one kind.

Information recording apparatus, information recording and reproducing apparatus and record medium

An apparatus records main information and sub information onto an information recording medium, which has a main recording area and a sub recording area. The apparatus is provided with an receiving device that receives the main information input from the external source; an accumulating device that accumulates the main information received by the receiving device; a recording device that records the main information and the sub information to the main recording area and the sub recording area, respectively; and a controller that determines whether or not an amount of the main information accumulated in the accumulating device is smaller than a predetermined amount, and that controls the recording device. In the apparatus, the recording device records the sub information to the sub recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is smaller than the predetermined amount, and the recording device records the main information to the main recording area under a control of the controller if the controller determines that the amount of the main information accumulated in the accumulating device is not smaller than the predetermined amount.

Information recording apparatus and information reproducing apparatus

An information recording apparatus records information including a plurality of information groups onto a recording medium. Each of the plurality of information groups includes a plurality of images. The apparatus has: a first recording device for recording the plurality of images onto the recording medium for each of the plurality of information groups; an reproduction device for reproducing the plurality of images for each of the plurality of the information groups, while the first recording device is recording the plurality of images onto the recording medium; a selection device for selecting one image from the plurality of images reproduced by the reproduction device as an identification image for identifying one of the plurality of information group in which the selected one image is included, while the first recording device is recording the plurality of images onto the recording medium; and a second recording device for recording at least either one of the identification image and information designating the identification image onto the recording medium.

An arbitrary desired reproducing time is set for reproducing information recorded on a recording medium, and an ordinary reproducing time is obtained based on management information recorded on the recording medium when the recorded information is reproduced at a standard reproducing speed. A skipping rate is calculated from the desired reproducing time and the ordinary reproducing time. A reproducing device is provided for reproducing the information recorded on the recording medium in the set desired reproducing time at the calculated skipping rate.
