TrackLength : TCDMSF	length of the track in MSF format.
TrackType : TTrackType	type of the track (possible values are ttAudio - for audio tracks and ttData for data tracks).

TCDPosition

Represents the current reader position on disc.

Properties

MSF	the position within a track in a MSF format.

Summary

Constants
EndOfDisc	This is a constant representing the logical position beyond the end of disc (very much like EOF for files).

Constants

EndOfDisc

This is a constant representing the logical position beyond the end of disc (very much like EOF for files).

TCDIn

This component reads data from CD-DA directly. It is suitable for creating CD-rippers. Descends from TAuInput. Requires CDRip.dll.

Summary

Functions

Functions

Eject

procedure Eject

Ejects CD-ROM drive’s tray.

CloseTray

procedure CloseTray

Closes CD-ROM drive’s tray.

Properties

DiscInfo

Read this property to get a TCDInfo about a disc in the drive.

Status

Read Status to get a TCDStatus about the drive.

Tracks

Returns information about a track specified by its number. The possible values of indexes range from 1 to TracksCount. The information about a track is returned as TCDTrackInfo record.

TracksCount

The number of tracks on the disc.

DriveName

The name of the current CD-ROM drive as returned by the drive unit.

DrivesCount

The total number of the CD-ROM drives detected in the system.

StartPos

Set this property to specify the starting position for data transfer in a TCDPosition format.

EndPos

Set this property to specify the end position for data transfer in a TCDPosition format. There is a special constant <EndOfDisc> of type TCDPosition If you want to record from a certain point to the end of disc, set this property value to <EndOfDisc>.

CurrentDrive

Use this property to set or get the number of the current CD-ROM drive. Possible values range from 0 to DrivesCount - 1.

StartTrack

Set StartTrack to specify the starting position for data transfer at the beginning of the track identified by number. The tracks are numbered starting from 1.

EndTrack

Set EndTrack to specify the ending position for data transfer at the end of the track identified by number. If you want to get data from a single track, the end track number should be the same as the start track number.
