Apparatus and method for automatically adjusting recording speed of a recorder

A method of automatically adjusting the recording speed of a recorder, which controls a servo microcomputer and an on-screen display (OSD) block by calculating a recordable time according to a remaining length of a recording medium by a signal from a reel rotation sensing means and a recording speed by the standard recording mode SP, and a recording time stored in a memory, the method comprising the steps of:

• storing said recording time in said memory after decoding received broadcast schedule data;
• obtaining a specific value by dividing said recording time by the recordable time;
• comparing said specific value with a predetermined reference value;
• automatically changing said recording speed when said specific value is equal to or less than said predetermined reference;
• and
• driving a warning signal when said specific value exceeds said predetermined reference.

• changing said recording speed when said specific value is equal to or less than said predetermined reference;
• and
• driving a warning signal when said specific value exceeds said predetermined reference, wherein said warning signal driving step further comprises the steps of:
• determining the shortage of said remaining medium length when said specific value exceeds three;
• generating a character warning signal, and recording said character warning signal with an indicator signal when said remaining length is short and the recording is in a reserved mode;
• and
• driving an alarm means and displaying the character warning signal on a monitor when said remaining length is short and said recording mode is not said reserved mode.
