摘要： A desired catch-up time at which reproduction started after a start of recording of input information catches up the recording is set. Recording start time, present time and recording end time are detected. A rate of the reproduction necessary to catch up the recording at the set catch-up time is determined recording start time, present time, and recording end time. The recorded information is reproduced at a determined rate until the set catch-up time.

摘要： 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.

摘要： In a disc player, a CAL pattern is recorded in a disc-like optical recording medium during a recording stand-by time period, which is yielded by a difference between a data rate in inputting information to a disc player 50 and a recording rate in recording information into the optical recording medium. The CAL pattern is reproduced from the optical recording medium, the reproduced pattern is evaluated, and an irradiation intensity of a laser beam is optimized for recording information in the optical recording medium, by a laser-output controller 30.

摘要： An information record medium (1: DVD) has a record track recorded with record information to be reproduced by an information reproducing apparatus (S2). The information reproducing apparatus is provided with a read device (80), and performs a reproduction while moving the read device along the record track at a predetermined reading linear velocity. The record information is divided into a plurality of first data groups (30: VOBU), each of which is a unit able to be accessed by the information reproducing apparatus, recorded on the record track. Lowest reading rate information (212) indicates a minimum requirement of a reading rate for the information reproducing apparatus to reproduce a reproduction unit, which comprises at least one of the first data groups and which is to be reproduced by the information reproducing apparatus such that a sequential logical meaning of the reproduction unit is continuous. The lowest reading rate information is recorded on the record track at one portion (LI, 11, 41) different from another portion where the record information is recorded.
