Abstract
An apparatus of recording data on a recording medium includes a pickup unit and a microcomputer. The pickup unit records data in a plurality of data frames included in a cluster. The microcomputer controls the pickup unit to record status information within the cluster, which indicates a status of the data being recorded in each data frame. In addition, the microcomputer further controls the pickup unit to record previous location information within the cluster when the cluster is determined to be a replacement cluster. The previous location information indicates a previous location of an original cluster associated with the replacement cluster.
Claims22
A method of recording data on a recording medium, the method comprising:
- recording data within a plurality of data frames included in a cluster;
- recording status information within the cluster for each data frame, the status information indicating a status of the data recorded in each data frame;
- and
- recording previous location information within the cluster when the cluster is determined to be a replacement cluster, the previous location information indicating a previous location of an original cluster associated with the replacement cluster.
A method of recording data on a recording medium, the method comprising:
- recording data within a plurality of data frames included in a cluster;
- recording status information within the cluster for each data frame, the status information indicating a status of the data recorded in each data frame;
- and
- recording first identification information within the cluster, the first identification information identifying the cluster as a replacement cluster or an original cluster.
A method of recording data on a recording medium, the method comprising:
- recording data within a plurality of data frames included in a cluster;
- and
- recording status information within the cluster for each data frame, the status information indicating a status of the data recorded in each data frame, wherein the status information indicates that the data recorded in each data frame represents any one of valid data, real-time data, padding data, and invalid data.
A method of reproducing a cluster recorded on a recording medium, the cluster having a plurality of data frames, the method comprising:
- extracting status information from the cluster, the status information indicating a status of data recorded in each data frame;
- and
- reproducing the data recorded in each data frame based upon the extracted status information, wherein the status information indicates that the data recorded in each data frame represents any one of valid data, real-time data, padding data, and invalid data.
An apparatus of recording data on a recording medium including a cluster having a plurality of data frames, the apparatus comprising:
- a pickup unit for recording data in the data frames;
- and
- a microcomputer for controlling the pickup unit to record status information within the cluster, the status information indicating a status of the data being recorded in each data frame, wherein the microcomputer further controls the pickup unit to record previous location information within the cluster when the cluster is determined to be a replacement cluster, the previous location information indicating a previous location of an original cluster associated within the replacement cluster.
An apparatus of reproducing a cluster recorded on a recording medium, the cluster having a plurality of data frames, the apparatus comprising:
- a pickup unit for reproducing data recorded in the data frames;
- and
- a microcomputer for controlling the pickup unit to extract status information from the cluster and to reproduce data recorded in each data frame based upon the extracted status information, wherein the status information indicates that the data recorded in each data frame represents any one of valid data, real-time data, padding data, and invalid data.
A recording medium comprising:
- a plurality of clusters, each cluster comprising:
- a first data area including a plurality of data frames;
- a second data area including status information for each data frame, the status information indicating a status of the data recorded in each data frame;
- and
- a third data area including previous location information when each cluster is determined to be a replacement cluster, the previous location information indicating a previous location of an original cluster associated with the replacement cluster.
