New firmware 1.0f provides option to change maximum read speed in Audio CD extraction.
CRW-F1 can extract audio tracks comfortably at a maximum speed of 44x. However, in rare cases, some bad-conditioned Audio CDs may unlocked from the disc holding mechanism and may be damaged, due to the fast rotation speed of the disc (8700 rpm).
Examples of these bad-conditioned discs include:
1) Unbalanced CDs such as ones labeled with sticker;
2) CDs with extremely thin clamp area (plastic area around the center hole) worn down after long time use.
The new firmware version 1.0f sets the default maximum read speed of Audio CDs at 24x (4700 rpm) for safe and stable audio extraction even with these bad-conditioned discs.
The speed limitation by this ‘safe mode’ can temporarily be removed by the following operations.
1) Open the disc tray and put an Audio CD;
2) Keep pressing the eject button for about five seconds;
3) Make sure the tray is properly closed, then let your finger away from the eject button;
4) Now CRW-F1 should read the Audio CD at a maximum speed of 44x (8700 rpm).
By re-opening the tray, the CRW-F1 goes back to the default ‘safe mode’ that reads the Audio CDs at a maximum speed of 24x (4700 rpm).
Please note that it is applied only to audio extraction from commercially available pressed Audio CDs. Below is a list of default maximum read speeds depending on the disc types with firmware version 1.0f.
Audio CD (commercially available pressed) max. 24x (4700 rpm) can be switched to max. 44x
CD-ROM (commercially available pressed) max. 44x (8700 rpm)
CD-R (audio/data) max. 44x (8700 rpm)
CD-RW (audio/data) max. 44x (8700 rpm)
