Sony SLV-M10HF Operating Instructions Manual page 87

Labelling a recorded program and tape (page 95)
You can attach an electronic "label" to the video tape and it's programs on
the SmartFile list. Labelling the recorded programs enables you to find a
program easily when you want to play it back. Also, once you label a
program which you set to record regularly (i.e. everyday, same day of a
week, etc.), the VCR recognizes the label and will automatically label all
future recordings of the same program.
Protecting a recorded program (page 100)
You can protect a recorded program from accidental over-recording or
erasure.
Erasing the data of an unwanted program (page 102)
By erasing a program from the SmartFile list, the VCR will record over the
unwanted program.
Storing program data from the DSS receiver
(Program Data Download) (page 103)
If you connect a DSS receiver equipped with the Program Data Download
function, you can store the program and category name transmitted from the
DSS on a SmartFile tape.
