What's the difference between 记录 and 纪录, both pronounced jìlù, and both meaning "record"? 记录 and 纪录 are both pronounced the same, and mean "record".  It looks like both can be used as nouns and verbs.

Question: What's the difference between 记录 and 纪录?

I'm using Zhongwen Chinese Popup Dictionary, and it says


  纪录: variant of 记录 (but in Taiwan, not for the verb sense "to record")


I understand that to mean 记录 and 纪录 mean the same thing, where 记录 is the default, and 纪录 is a variant (except in Taiwan).  However, I'm not sure this is accurate.

Finding some examples online, we have...


纪录


  吉尼斯世界纪录 (source)
  Guinness world record
  
  破马拉松纪录奖励100万 (source)
  Break China's marathon record reward 1,000,000 [Chinese yuan]

记录


  幼儿教师观察记录 (source)
  Kindergarten teacher observation records
  
  微信记录怎么彻底删除 (source)
  How [do I] thoroughly delete Weixin records?



They do seem a bit different, but it's very unclear to me.
Both 记录 and 纪录 can be a noun for "record" or a verb for "to record"


  紀 has the meaning of "historical record"; "epoch; period; age"



纪录(n) is more often used for "record" (of historical fact).  e.g. 目前男子一百米短跑世界[紀錄]为 9.58 秒; 多倫多最低氣溫[紀錄]是 −33 °C 
纪录(v) is more often used for "to record" (historical item). e.g. "资治通鉴[纪录]了由公元前 403年 至 公元 959年的 1362 年歴史"
记录(n) is appropriate term for any information that's being recorded e.g. 查看通话[记录]
记录(v) applies to recorded information in general. e.g. 打卡机的功能是[记录]員工的上下班時間
