Towards the center, at the end of the groove, there is another wide-pitched section known as the lead-out. At the very end of this section the groove joins itself to form a complete circle, called the lock groove; when the stylus reaches this point, it circles repeatedly until lifted from the record. On some recordings (for example Sgt. Pepper's Lonely Hearts Club Band by The Beatles, Super Trouper by Abba and Atom Heart Mother by Pink Floyd), the sound continues on the lock groove, which gives a strange repeating effect. Automatic turntables rely on the position or angular velocity of the arm, as it reaches the wider spacing in the groove, to trigger a mechanism that lifts the arm off the record. Precisely because of this mechanism, most automatic turntables are incapable of playing any audio in the lock groove, since they will lift the arm before it reaches that groove.

What is the center where the data joins to complete a circle?
Answer: lock groove

Many Somerset soldiers died during the First World War, with the Somerset Light Infantry suffering nearly 5,000 casualties. War memorials were put up in most of the county's towns and villages; only nine, described as the Thankful Villages, had none of their residents killed. During the Second World War the county was a base for troops preparing for the D-Day landings. Some of the hospitals which were built for the casualties of the war remain in use. The Taunton Stop Line was set up to repel a potential German invasion. The remains of its pill boxes can still be seen along the coast, and south through Ilminster and Chard.

In the years after World War II, the Japanese government also instituted a series of orthographic reforms. Some characters were given simplified forms called shinjitai (lit. "new character forms", the older forms were then labelled the kyujitai , lit. "old character forms"). The number of characters in common use was restricted, and formal lists of characters to be learned during each grade of school were established, first the 1850-character toyo kanji list in 1945, the 1945-character joyo kanji list in 1981, and a 2136-character reformed version of the joyo kanji in 2010. Many variant forms of characters and obscure alternatives for common characters were officially discouraged. This was done with the goal of facilitating learning for children and simplifying kanji use in literature and periodicals. These are simply guidelines, hence many characters outside these standards are still widely known and commonly used, especially those used for personal and place names (for the latter, see jinmeiyo kanji),[citation needed] as well as for some common words such as "dragon" (Japanese kana: , Romaji: tatsu) in which both the shinjitai and the kyujitai forms of the kanji are both acceptable and widely known amongst native Japanese speakers.

When was the 2136 character reformed?
Answer:
2010
