In the interview he says, "I started writing when I was thirteen." Elena Cepcekova, writer, sent his first verses written for Mladost magazine back to him. After that he became even more determined to write. Elena Cepcekova appreciated his poems later. Banga continued writing during his studies at a teachers' college in Krupina. He made every effort to master the language, and the secrets of writing good poems. However, academic studies would not have had any sense if he had not been talented.

He studied Slovak and history at the Philosophical Faculty of Comenius University in Bratislava. During his studies he met many significant Slovak poets. Jan Simonovic, Stefan Strazay, Vlastimil Kovalcik, Jan Stacho, and Jan Ondrus were among them. Banga believed that Jan Stacho was the founder of modern Slovak poetry. He became a member of a literary club lead by Jan Stevcek. As many other poets, he had high regard for Milan Rufus. He still considers him to be the best living Slovak poet.

At the end of his studies in 1963 he had his first collection of poems ready for publication. He translated and did poetic adaptations of Romani stories. After it had been edited by Pavol Horov and Milan Kraus, his collection, titled Piesen nad vetrom (A Song above the Wind), was published. Literary critics said it was an uncommon, special poetic voice.

In 1963 he started teaching at a secondary school - a Gymnasium in Trebisov. He regreted his distance from the Bratislava bohemians - Albin Brunovsky, painter; Ilja Zelienka, composer; Ivan Macak, music critic; Vojtech Kondrot, Marian Kovacik, Jozef Gerboc and others.

During this time he published his second collection, Zaruzlie a lekno (Marsh Marigold and Water Lily, 1967), and he also wrote interesting stories about the life of Gypsies for Kulturny zivot magazine (Cultural Life). Those pieces may have been preparation for his writing the fairy tales titled Cierny vlas (Black Hair, 1970) which were illustrated by Ferdinand Hloznik. The collection Rozhovory s nocou (Talks with the Night, 1970) won the Smena Publishing House award. Simultaneously another collection, Modra burka (Blue Storm), appeared and he decided to change jobs. He left teaching and became a script editor for the Kosice TV Studio and worked on the editorial board for children and youth. He was particularly concerned with fairy tales. He himself wrote several successful bedtime stories, e.g. "Little Snake Bubienok" from Fairy Tales from a Forest Meadow, The Shop in the Meadow... He also wrote the scripts for fairy tales from his book Cierny vlas: "The Brickmaker and the King", "The Girl with Roses in Her Footsteps"...

Dezider Banga says that even the greatest talent is lost without diligence and honesty in writing. He himself had to work very hard. However, his publishers and also his wife were very patient with him. He longed to return to Bratislava. He made his dream come true and started working in the Palace Publishing House which published encyclopedias. Later he became a commentator on culture for an international radio broadcast, worked for the Nova cesta magazine, and later as its editor-in-chief. He was so absorbed in this work that his collection Horiaca visna (A Sour Cherry Tree on Fire) did not appear until 1982. It was awarded the Slovensky Vydavatel Publishing House prize as the best book of the year. The award was presented by writer Vladimir Minac. His completed collection Magnonlie zhasinaju (Magnolias Fade) was published in 1989 and collected Lyrika (Lyric Poems) in 1992. Dezider Banga says that people would be sad without poetry. If they are governed by modern technology they will hardly find the "earthen lantern" to hold it up to see the way. At the moment Banga is preparing another collection which may appear in the publishing house of one of his three sons.

After 1989 Banga became the chair of the Roma Culture Organisation. He publishes the children's magazine Luludi and ROMA magazine for adults and is their editor-in-chief. He has also compiled a spelling book. He believes that Gypsies will educate themselves. He writes both in Slovak and Romani. As to the young Roma authors he likes Elena Lackova the best. She was the first Roma graduate of the Charles University in Prague; He is also fond of Jozef Ravasz and Katarina Patockova, a young poet.
