Abstract
A read-only information storage medium having one or more recording layers and a method and apparatus reading/reproducing data, the read-only information storage medium having one or more recording layers, each layer containing a lead-in area, a user data area, and a lead-out area. The locations of the lead-in and lead-out areas may be fixed, and when an amount of user data recorded on the storage medium is less than a full capacity of the storage medium, data other than the user data is recorded on a space remaining after the user data has been recorded.
Claims29
A read-only information storage medium having one or more recording layers, each layer containing a lead-in area, a user data area including user data, and a lead-out area, wherein locations of the lead-in and lead-out areas are disposed at a predetermined, fixed location, and since an amount of user data recorded on the storage medium is less than a full capacity of the storage medium, data other than the user data is recorded on a space remaining after the user data has been recorded in the user data area.
A read-only information storage medium having one or more recording layers, each layer containing a lead-in area, a user data area including user data, and a lead-out area, wherein locations of the lead-in and lead-out areas are disposed at a predetermined, fixed location, and since an amount of the user data recorded on the storage medium is less than a full capacity of the storage medium, a space remaining on the storage medium after the user data has been recorded is maintained as a mirror region.
A read-only information storage medium having a plurality of recording layers, each layer containing a lead-in area, a user data area including user data, and a lead-out area, wherein since an amount of the user data recorded on the storage medium is less than a full capacity of the storage medium, a location of the lead-out area of a recording layer on which the user data is recorded last is variable while locations of the other lead-in and/or lead-out areas are fixed in corresponding predetermined areas.
A method of transferring data with respect to a read-only information storage medium having one or more recording layers, each layer containing a lead-in area, a user data area, and a lead-out area, the method comprising:
- fixing locations and capacities of the lead-in and lead-out areas;
- and
- when an amount of user data recorded on the storage medium is less than a full capacity of the storage medium, recording data other than the user data on a remaining space after the user data has been recorded or maintaining the remaining space as a mirror region.
An apparatus transferring data with respect to a read-only information storage medium having one or more recording layers, each layer containing a lead-in area, a user data area, and a lead-out area, the apparatus comprising:
- a pickup emitting a beam onto the information storage medium and receiving a beam reflected from the information storage medium;
- a recording/reproducing signal processor receiving the beam reflected from the information storage medium through the pickup in order to perform signal processing;
- and
- a controller controlling the pickup to transfer data from predetermined, fixed locations and fixed capacities of the lead-in and lead-out areas and, when an amount of user data recorded on the storage medium is less than a full capacity of the storage medium, to transfer data other than the user data with respect to a remaining space after the user data has been recorded or maintain the remaining space as a mirror region.
A read-only information storage medium, comprising:
- a recording layer containing a lead-in area, a user data area including user data in a first area and a remaining area, and a lead-out area, wherein locations of the lead-in and lead-out areas are disposed at predetermined fixed locations, and data other than the user data is recorded on a remaining space after the user data has been recorded in the user data area.
