Abstract
A controller 10 carries out a control such as to divide a cache memory 8 for temporarily storing data when recording and/or reproducing the data on a data recordable optical disk 11, into a plurality of memory areas, i.e., a recording data storage memory area and a verifying data storage area, and storing data therein.
Claims36
An information recording apparatus comprising:
- temporary storage means temporarily storing data in a data recordable information recording medium on the occasion of recording and/or reproduction;
- and control means dividing a storage area of said temporary storage means to a plurality of areas according to a mode of recording the data in said information recording medium, wherein:
- recording means for recording data in the recording area of said information recording medium and reproducing means for reproducing data recorded in the recording area of the information recording medium are provided;
- said control means divides the storage area of said temporary storage means into at least a recording data storage area storing data to record in the information recording medium and a reproduced data storage area storing data reproduced from the information recording medium;
- storing the data to record in the information recording medium in said recording data storage area;
- and, when a reproduction request is received during recording by said recording means, said reproducing means is made to store data reproduced from the information recording medium in said reproduced data storage area;
- and
- said recording means keeps a waiting state of waiting before starting data recording until a data occupation amount in said recording data storage area reaches a predetermined threshold, enters a recording state starting the data recording when the data occupation amount exceeds the predetermined threshold, and records data in the recording area of the information recording medium;
- and
- means for immediately causing the reproducing means to reproduce data when a reproduction request is received during the waiting state is provided.

An information recording method comprising:
- a control step of dividing a storage area of a temporary storage means temporarily storing data in a data recordable information recording medium on the occasion of recording and/or reproduction, into a plurality of areas according to a mode of recording of the data in said information recording medium, wherein:
- a recording step of recording data in the recording area of said information recording medium and a reproducing step of reproducing data recorded in the recording area of the information recording medium are provided;
- and said control step comprises a step of dividing the storage area of said temporary storage means into at least a recording data storage area storing data to record in the information recording medium and a reproduced data storage area storing data reproduced from the information recording medium;
- and, when a reproduction request is received during recording in said recording step, data reproduced from the information recording medium is stored in said reproduced data storage area in said reproducing step,
- said recording step comprises a step of keeping a waiting state of waiting before starting data recording until a data occupation amount in said recording data storage area reaches a predetermined threshold, entering a recording state starting the data recording when the data occupation amount exceeds the predetermined threshold, and recording data in the recording area of the information recording medium;
- and a step of immediately reproducing data in the reproducing step when a reproduction request is received during the waiting state in the recording step, is provided.

A recording medium recording a program for causing a computer to execute a control step of dividing a storage area of temporary storage means temporarily storing data in data recordable information recording medium on the occasion of recording and/or reproduction, into a plurality of areas according to a mode of recording of the data in said information recording medium, wherein:
- a recording step of recording data in the recording area of said information recording medium and a reproducing step of reproducing data recorded in the recording area of the information recording medium are provided;
- and said control step comprises a step of dividing the storage area of said temporary storage means into at least a recording data storage area storing data to record in the information recording medium and a reproduced data storage area storing data reproduced from the information recording medium;
- and, when a reproduction request is received during recording in said recording step, data reproduced from the information recording medium is stored in said reproduced data storage area in said reproducing step;
- and
- said recording step comprises a step of keeping a waiting state of waiting before starting data recording until a data occupation amount in said recording data storage area reaches a predetermined threshold, entering a recording state starting the data recording when the data occupation amount exceeds the predetermined threshold, and recording data in the recording area of the information recording medium;
- and a step of immediately reproducing data in the reproducing step when a reproduction request is received during the waiting state in the recording step, is provided.
3 more elements
The recording medium recording the program claimed in 25, wherein:
- said control step comprises a step of setting a size of said reproduced data storage area so that said size becomes smaller than the recording data storage area.
