def delete_student_record() -> None:
    """
    Delete a student record from the binary data file 'studrec.dat' based on the provided roll number.
    
    This function performs the following operations:
    1. Reads the current student records from 'studrec.dat'
    2. Prompts the user to enter a roll number to delete
    3. Removes the record with the specified roll number
    4. Writes the updated records back to 'studrec.dat'
    
    Each student record is stored as a tuple in the format: (roll_number, ...)
    
    Raises:
        FileNotFoundError: If 'studrec.dat' does not exist.
        pickle.UnpicklingError: If the file contains corrupted data.
        ValueError: If the user input cannot be converted to an integer.
