Method for recording multiple data segments on a storage disc with eccentricity factor

A method of recording data on a high-density, optical disc having a plurality of tracks therein, comprising:

• (a) recording first data in a first portion of said tracks on said optical disc;
• (b) recording a first reference file associated with said first data in a second portion of said tracks adjacent to said first portion;
• (c) recording a second reference file in a third portion of said tracks adjacent to said second portion;
• said third portion including a last recording track;
• (d) recording a character which is repeated in a fourth portion of said tracks adjacent to said last recording track to thereby signify the end of said first data and associated first and second reference files;
• (e) leaving a recording gap on said optical disc between said fourth portion and a fifth portion which will be subsequently used for recording subsequent data;
• (f) repeating said steps (a) through (d) for said subsequent data;
• and
• said step of leaving a recording gap comprising determining an eccentricity factor for said optical disc in relation to a means for recording and a means for reading said optical disc and leaving a predetermined approximate number of tracks between said fourth portion and said fifth portion in conformance with said eccentricity factor.

A method of recording data on a high-density, optical disc having a plurality of tracks therein, comprising:

• recording first data in a first portion of said tracks on said optical disc;
• recording at least a first reference file associated with said first data in a second portion of said tracks adjacent to said first portion, said second portion including a last recording track;
• recording a character which is repeated in a third portion of said tracks adjacent to said last recording track to thereby signify the end of said first data and the associated first reference file;
• storing said optical disc when no additional data is to be recorded thereon;
• retrieving said optical disc when additional data is to be recorded thereon;
• reading said retrieved optical disc until a said third portion of said tracks is encountered, and thereafter,
• leaving a predetermined approximate number of tracks between said third portion of said tracks and a fourth portion of said tracks to provide a recording gap therebetween;
• repeating said recording steps for second data by beginning the recording of said second data at said fourth position;
• and
• said leaving step comprising determining an eccentricity factor for said optical disc in relation to a means for recording and a means for reading said optical disc and leaving about 15 said tracks for said recording gap in conformance with said eccentricity factor.
