The main characteristics of CD-ROM specification are:

1. CD Data Structure: Data on CD is stored in units of sectors. Each sector holds 2352 bytes of data, and is divided into 98 frames with 24 bytes per frame. This data structure is shared by both audio CD and data CD.

2. Data Track: Data (audio and data) is recorded on CD as tracks.

3. Track Type: There are three track types:

  • CD-Audio: For audio music.
  • CD-ROM Mode 1: For computer data.
  • CD-ROM Mode 2: For compressed picture, audio or video data.
